The responsibility of the inbound authenticator component is to identify and parse all the incoming authentication requests and then build the corresponding response. A given inbound authenticator has two parts:

  • Request Processor
  • Response Builder

For each protocol supported by the WSO2 Identity Server, there should be an inbound authenticator. The Identity Server includes inbound authenticators for SAML 2.0, OpenID Connect, OAuth 2.0, Kerberos KDC, WS-Trust STS and WS-Federation (passive). The responsibility of the SAML 2.0 request processor is to accept a SAML request from a service provider, validate the SAML request and then build a common object model understood by the authentication framework and handover the request to it. The responsibility of the SAML response builder is to accept a common object model from the authentication framework and build a SAML response out of it.

Both the request processors and the response builders are protocol aware, while the authentication framework is not coupled to any protocol. See Architecture for more information on the complete flow where inbound authenticators come into play.

To register a service provider, do the following.

  1. Log in to the Management Console
  2. Navigate to the Main menu to access the Identity menu. Click Add under Service Providers.
  3. Fill in the Service Provider Name and provide a brief Description of the service provider. Only Service Provider Name is a required field.

    The Service Provider Name should not contain any special characters except for fullstops (.), hyphens (-), underscores (_) and spaces.

  4. Click Register to add the new service provider.

    Note: When a service provider is created, it is assigned to a "APPLICATION" role (for instance, if you add Travelocity as the service provider, then the role will look like "Application/travelocity"). Users who wish to manage the created service provider should have this application role assigned. See Configuring Roles for guidance on how to do this.

  5. The Service Providers screen appears. Paste the application's certificate to the Application Certificate field.  

    When is this certificate used

    This certificate is used to validate the signatures of the signed requests from the application (service provider) to the Identity Server. Therefore, the certificate is used in below scenarios:

    Format of the certificate

    WSO2 IS expects the certificate to be in PEM format.

    PEM is a Base64 encoded format, therefore contains ASCII character and easier to deal with rather than a binary encoded certificate.

    How to obtain the PEM encoded certificate

    The PEM content of a certificate in a JKS file, can be obtained by following the steps below:

    1. Export the certificate from the keystore. The exported certificate will be in binary format.

    keytool -export -keystore <keystore-path> -alias <alias-of-the-certificate> -file <path-of-the-expected-certificate-file>
    e.g. keytool -export -keystore wso2carbon.jks -alias wso2carbon -file wso2carbon.crt

    2. Convert the above binary encoded certificate to a PEM encoded certificate

    openssl x509 -inform der -in <path-of-binary-certificate> -out <path-of-expected-pem-content>
    e.g. openssl x509 -inform der -in wso2carbon.crt -out wso2carbon.pem

    Note: You can paste the public certificate in to the given text area or upload file in PEM format. If the Application Certificate field is left blank, WSO2 IS is backward compatible and follows the previous implementation to locate the certificates in the keystore.
    This means that if it is a SAML SSO flow, the certificate alias mentioned in SAML inbound authentication configuration is used when the certificate is not updated via the management console. If it is an OIDC request object signature validation, the certficate will be retrived from default keystore, aliase to consumer key of the auth application.

  6. Select if the service provider is a SaaS Application or not using the Saas Application checkbox. The SaaS Application configuration defines which users you want to be able to log into your web application.

    Tip: By default, the SaaS Application check box is disabled, which means the web application is not shared among tenants so only users in the current tenant (the one you use to define the service provider) will be allowed to log into the web application. Alternatively, if you enabled the SaaS Application check box, that means this web application is shared among tenants so users from any tenant will be allowed to log into the web application. For example, if there are three tenants, namely TA, TB and TC and the service provider is registered and configured only in TA.

    • If the SaaS Application configuration is disabled, only users in TA are able to log into the web application.

    • If the SaaS Application configuration is enabled, all TA, TB, TC users are able to log into the web application.

    • For more information on creating and managing tenants, see Creating and Managing Tenants.

You can configure the following for inbound authentication.

Removed Feature!

OpenID 2.0 has been removed from the base product in WSO2 Identity Server version 5.3.0 onwards as it is now an obsolete specification and has been superseded by OpenID Connect. Alternatively, we recommend that you use OpenID Connect. 

 SAML2 Web SSO Configuration

  1. Expand the SAML2 Web SSO Configuration and click Configure.
  2. Select one of the following modes:

Metadata and URL configuration

When configuring a service provider (SP) or a federated identity provider (Federated IdP), the user is required to enter configuration data to facilitate exchanging authentication and authorization data between entities in a standard way. Apart from manual entering of configuration data, WSO2 IS allows you to upload configuration data using a metadata XML file or refer to a metadata XML file located in a predetermined URL. These two methods of uploading configuration data enable faster entry of configuration data because it allows the user to use the same metadata xml file for multiple instances of entity configuration. In addition to SAML metadata upload, WSO2 IS also supports SAML metadata download for the resident identity provider.

Manual configuration

  1. Select Manual Configuration and fill in the form that appears.
  2. Click Register.

The following points should be taken into consideration when filling the above New Service Provider form.

FieldDescriptionSample value
IssuerSpecify the Issuer. This is the <saml:Issuer> element that contains the unique identifier of the service provider. This is also the issuer value specified in the SAML Authentication Request issued by the service provider. When configuring single-sign-on across Carbon servers, ensure that this value is equal to the ServiceProviderID value mentioned in the <IS_HOME>/repository/conf/security/authenticators.xml file of the relying party Carbon
Assertion Consumer URLsSpecify the Assertion Consumer URLs. This is the URL to which the browser should be redirected to after the authentication is successful. This is the Assertion Consumer Service (ACS) URL of the service provider. The identity provider redirects the SAML2 response to this ACS URL. However, if the SAML2 request is signed and SAML2 request contains the ACS URL, the Identity Server will honor the ACS URL of the SAML2 request. It should have this format: https://(host-name):(port)/acs. You can add multiple assertion consumer URLs for the service provider by entering the URL and clicking the Add button.http://wso2is.local:8080/
Default Assertion Consumer URL

Since there can be multiple assertion consumer URLs, you must define a Default Assertion Consumer URL in case you are unable to retrieve it from the authentication request.

Tip: In a service provider initiated single sign-on setup, the following needs to be considered.

  • If no ACS URL is given in the <AuthnRequest>, the Identity Server sends the response to the default ACS URL of the service provider (whether the request is signed or not).
  • If the ACS URL in <AuthnRequest> matches with one of the registered URLs, the Identity Server sends the response to the matched one. 
  • If the ACS URL in <AuthnRequest> does not match any of the registered ACS URLs and if the request is signed, the Identity Server sends the response to the ACS URL in the request only if the signature is valid. Alternatively, the <AuthnRequest> is rejected.

In an identity provider initiated single sign-on setup, the following needs to be considered.

  • If the “acs” query parameter is not present in the request, the Identity Server sends the response to default ACS URL of the service provider.
  • If the "acs” parameter is present and the value of that parameter matches with any of the registered ACS URLs of the service provider, then the Identity Server sends the response to the matched one.
NameID format

Specify the NameID format. This defines the name identifier formats supported by the identity provider. The service provider and identity provider usually communicate with each other regarding a specific subject. That subject should be identified through a Name-Identifier (NameID) , which should be in some format so that It is easy for the other party to identify it based on the format. Name identifiers are used to provide information regarding a user. 

About NameID formats

For SSO interactions, you can use the following types of NameID formats.

  • urn:oasis:names:tc:SAML:2.0:nameid-format:persistent
  • urn:oasis:names:tc:SAML:2.0:nameid-format:transient
  • urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress
  • urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified
  • urn:oasis:names:tc:SAML:1.1:nameid-format:X509SubjectName
  • urn:oasis:names:tc:SAML:1.1:nameid-format:WindowsDomainQualifiedName
  • urn:oasis:names:tc:SAML:2.0:nameid-format:kerberos
  • urn:oasis:names:tc:SAML:2.0:nameid-format:entity

This specifies the name identifier format that the Identity Server wants to receive in the subject of an assertion from a particular identity provider. The following is the default format used by the identity provider.

  • urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress


Certificate Alias

Select the Certificate Alias from the dropdown. This is used to validate the signature of SAML2 requests and is used to generate encryption. Basically the service provider’s certificate must be selected here. Note that this can also be the Identity Server tenant's public certificate in a scenario where you are doing a tenant specific configuration.

From WSO2 IS 5.5.0 onwards, the .pem certificate can be updated via the Service Provider screen in the management console UI using the Application Certificate field. If the certificate has been entered in the Application Certifiate field, the system will use the certificate given there and override the certificate alias field.

However, if the Application Certificate field has been left blank, the certificate specified in Certificate Alias will be used.

Response Signing Algorithm

Specifies the ‘SignatureMethod’ algorithm to be used in the ‘Signature’ element in POST binding. The default value can be configured in the <IS_HOME>/repository/conf/identity.xml file, in the SSOService element with SAMLDefaultSigningAlgorithmURI tag. If it is not provided the default algorithm is RSA­SHA 1, at URI ‘­sha1' .­sha1 
Response Digest Algorithm

Specifies the ‘DigestMethod’ algorithm to be used in the ‘Signature’ element in POST binding. The default value can be configured in the <IS_HOME>/repository/conf/identity.xml file, in the SSOService element with SAMLDefaultDigestAlgorithmURI tag. If it is not provided the default algorithm is SHA 1, at URI ‘ .
Assertion Encryption AlgorithmThe algorithm that the SAML2 assertion is encrypted. The default value can be configured in the <IS_HOME>/repository/conf/identity.xml file, in the SSOService element with SAMLDefaultAssertionEncryptionAlgorithm URI tag. The default is
Key Encryption AlgorithmThe algorithm that the SAML2 key is encrypted. The default value can be configured in the <IS_HOME>/repository/conf/identity.xml file, in the SSOService element with SAMLDefaultKeyEncryptionAlgorithm URI tag. The default algorithm is
Enable Response SigningSelect Enable Response Signing to sign the SAML2 Responses returned after the authentication process.Selected
Enable Signature Validation in Authentication Requests and Logout Requests Select Enable Signature Validation in Authentication Requests and Logout Requests if you need this functionality configured. This specifies whether the identity provider must validate the signature of the SAML2 authentication request and the SAML2 logout request that are sent by the service provider. Unselected
Enable Assertion EncryptionEnable Assertion Encryption, if you wish to encrypt the assertion.Unselected
Enable Single LogoutSelect Enable Single Logout so that all sessions are terminated once the user signs out from one server. If single logout is enabled, the identity provider sends logout requests to all service providers. Basically, the identity provider acts according to the single logout profile. If the service provider supports a different URL for logout, you can enter a SLO Response URL and SLO Request URL for logging out. These URLs indicate where the request and response should go to. If you do not specify this URL, the identity provider uses the Assertion Consumer Service (ACS) URL. Selected
Enable Attribute Profile Select Enable Attribute Profile to enable this and add a claim by entering the claim link and clicking the Add Claim button. The Identity Server provides support for a basic attribute profile where the identity provider can include the user’s attributes in the SAML Assertions as part of the attribute statement. Once you select the checkbox to Include Attributes in the Response Always, the identity provider always includes the attribute values related to the selected claims in the SAML attribute statement.Unselected
Enable Audience RestrictionSelect Enable Audience Restriction to restrict the audience. You may add audience members using the Audience text box and clicking the Add button.Unselected
Enable Recipient Validation Select this if you require validation from the recipient of the response.Unselected

Enable IdP Initiated SLOSelect the Enable IdP Initiated SLO checkbox to enable this functionality. You must specify the URL.Unselected
Enable Assertion Query Request ProfileSelect the Enable Assertion Query Request Profile checkbox to query assertions that are persisted to the database when you login to the service provider application. For more information, see Querying SAML Assertions.Unselected

Metadata file configuration

This option allows you to provide the configuration data required for configuring SAML2, by uploading a metadata .xml file instead of having to manually enter the values. This enables faster entry of configuration data and allows the user to use the same metadata XML file for multiple instances of entity configuration. 

  1. Select Metadata File Configuration. 
  2. Click Choose File, and select the .xml file containing the metadata for the service provider SAML configuration. 
  3. Click Upload

    From WSO2 IS 5.5.0 onwards, the certificate can be added via the Service Providers screen in the management console UI using the Application Certificate field. This means that certificates can now be directly added along with the service provider instead of having to import the certificate to the keystore and referring to it using the Certificate Alias field.

    Therefore, when uploading a metadata file, the Application Certificate field in the Service Providers screen will automatically display the certificate that is embedded in the metatdata file. You can update or edit the certificate by editing the content within the Application Certificate field and uploading the metadata file again will override the existing certificate.

URL configuration

Metadata for a service provider may be published in a well known location via a URI. This option allows you to provide the configuration data required for configuring SAML2, by providing a URI(Ex: "") instead of having to manually enter the values. This enables faster entry of configuration data and allows the user to use the same metadata XML file for multiple instances of entity configuration. 

  1. Select URL Configuration and enter the URL containing the service provider metadata.

 OAuth/OpenID Connect Configuration

OAuth 2.0 has three main phases. They are; requesting an Authorization Grant, exchanging the Authorization Grant for an Access Token and accessing the resources using this Access Token. OpenID Connect is another identity layer on top of OAuth 2.0. OAuth applications can get authentication event information over the IDToken and can get the extra claims of the authenticated user from the OpenID Connect UserInfo endpoint.

To enable OAuth support for your client application, you must first register your application. Follow the instructions below to add a new application.

Let's get started to configure the service provider you created!

  1. Expand the Inbound Authentication Configuration section and then expand OAuth/OpenID Connect Configuration. Click Configure.
  2. Fill in the form that appears. For the Allowed Grant Types you can disable the ones you do not require or wish to block.

    Note: The grant type highlighted below is a custom grant type. This will only appear on the UI if you have configured the JWT grant type. The value specified in the <GrantTypeName> property of the identity.xml file when creating the custom grant type is the value that will appear on the UI. For more information on writing a custom grant type, see Writing a Custom OAuth 2.0 Grant Type.

    When filling out the New Application form, the following details should be taken into consideration.

    OAuth Version

    Selecting OAuth Version as 1.0a removes all the configurable Allowed Grant Types. This is because this version of OAuth does not support grant types.

    Callback Url

    This is the exact location in the service provider's application where an access token would be sent. This is a required field (if the grant type is anything other than 'Code' or 'Implicit') and it is important to configure, as it is imperative that the service provider receives the access token. This is necessary for security purposes to ensure that the token is not compromised.

    Configure multiple callback URLs

    From IS 5.2.0 onwards, regex-based consumer URLs are supported when defining the callback URL. This enables you to configure multiple callback URLs for one application by entering a regex pattern as the value for the callback URL field.
    For example, if you have two service providers that use the same application, you can now define a regex pattern which will work for both callback URLs instead of having to configure two different applications for the two service providers. Assume the two callback URLs for your two service providers are as follows:

    To configure the callback URL to work for both of these URLs, set it using a regex pattern as follows:


    You must have the prefix 'regexp=' before your regex pattern. To define a normal URL, you can specify the callback URL without this prefix.

    You can also configure a regex pattern that contains dynamic values as seen below.

    Allowed Grant Types - The following are the grant types that are used to get the access token:

    Entering the username and password required at the service provider will result in a code being generated. This code can be used to obtain the access token. For more information on this grant type, see this Authorization Code specification.


    This is similar to the code grant type, but instead of generating a code, this directly provides the access token. For more information on this grant type, see this Implicit Grant specification.


    This authenticates the user using the password provided and the access token is provided. For more information on this grant type, see this Resource Owner Password Credentials Grant specification.

    Client CredentialThis is the grant type for the client key and client secret. If these two items are provided correctly by the service provider, the access token is sent. For more information on this grant type, see this Client Credentials specification.
    Refresh Token This will enable the user to obtain an access token by using the refresh token once the originally provided access token is used up. For more information on this grant type, see this Refresh Token specification.

    This uses SAML assertion to obtain the access token. For more information on this grant type, see this SAML2 Bearer specification.

    IWA-NTLMThis is similar to the password grant type, but it is specific to Microsoft Windows users.
    urn:ietf:params:oauth:grant-type:jwt-bearerThis is a custom grant type. It uses a JWT token to obtain the access token. For more information about this grant type, see this JWT specification.
    PKCE MandatorySelect this if you are using the Code grant type. PKCE is a recommended security measure used to mitigate a code interception attack. See Mitigating Authorization Code Interception Attacks for more information.
    Support PKCE 'Plain' Transform AlgorithmSelect this if you are using PKCE.

    User Access Token Expiry Time, Application Access Token Expiry Time, Refresh Token Expiry Time, Id Token Expiry Time

    Set the validity period (in seconds) for User Access Token, Application Access Token, Refresh Token, and Id Token.
    Enable Audience Restriction

    Select this to enable audience restrictions for OAuth applications. If necessary, you can add multiple audiences. To add an audience, specify a required Audience value and click Add. All audience values that you add would be available in the ID token generated for the corresponding application.

    Before you add an audience, ensure that the following property is set to true in the <IS_HOME>/repository/conf/identity/identity.xml file.

  3. Click Add. The following information is added for your service provider.
    • OAuth Client Key - This is the client key of the service provider, which will be checked for authentication by the Identity Server before providing the access token.
    • OAuth Client Secret - This is the client secret of the service provider, which will be checked for authentication by the Identity Server before providing the access token. Click the Show button to view the exact value of this.
    • Actions - 
      • Edit: Click to edit the OAuth/OpenID Connect Configurations

      • Revoke: Click to revoke (deactivate) the OAuth application. This action revokes all tokens issued for this application. In order to activate the application, you have to regenerate the consumer secret. 

      • Regenerate Secret: Click to regenerate the secret key of the OAuth application. 

      • Delete: Click to delete the OAuth/OpenID Connect Configurations


    The OAuth Client Key and OAuth Client Secret are stored as plain text values by default. Here, the Client Secret is stored as a random number generated using two UUIDs and HMAC-SHA1 hash function, which is known to resist the strongest attack known against HMAC.
    If you want to change the format in which the client secret is stored, you need to change the <TokenPersistenceProcessor> property in the <IS_HOME>/repository/conf/identity/identity.xml file depending on how you want to store tokens. For information on possible values that you can specify as <TokenPersistenceProcessor> based on your requirement, see Supported token persistence processors.

    Once you configure a required token persistence processor, be sure to restart the server for the changes to be applied to WSO2 Identity Server.

 WS-Federation (Passive) Configuration

WSO2 Identity Server's passive security token service (Passive STS) is used as the WS-Federation implementation. The Passive STS is capable of issuing SAML 1.1 and 2.0 security tokens.

To request a SAML 2.0 security token, the Request Security Token (RST) should be sent to the passive STS endpoint with the TokenType 'SAMLV2.0' when sending the token request. If there is no RST specified, WSO2 Identity Server will issue a SAML 1.1 token by default.

Configuring passive STS

  1. See here for details on adding a service provider. 
  2. Expand the Inbound Authentication Configuration followed by the WS-Federation (Passive) Configuration section and provide the following values.

    • Passive STS Realm - This should be an unique identifier for the web app. Provide the same realm name given to the web app you are configuring WS-Federation for.

    • Passive STS WReply URL - Provide the URL of the web app you are configuring WS-Federation for.  This endpoint URL will handle the token response. 


      If you want to configure an expiration time for the security token, you need to add the following configuration in the <IS_HOME>/repository/conf/carbon.xml file, under the <Server> element:


      Here, the expiration time should be specified in milliseconds.

  3. Expand the Claim Configuration section and map the relevant claims. See Configuring Claims for a Service Provider for more information. 
  4. Click Update to save changes. 

Currently the signing algorithm used for passive STS by default is rsa-sha1 and the digest algorithm used is sha1. To change the default algorithms, add the following configuration under the <security> tag in the carbon.xml file found in the <IS_HOME>/repository/conf directory. The example given below sets the signing algorithm to rsa-sha256 and the digest algorithm to sha256.


To configure this, apply the 3640 WUM update to WSO2 IS 5.6.0 using the WSO2 Update Manager (WUM). To deploy a WUM update into production, you need to have a paid subscription. If you do not have a paid subscription, you can use this feature with the next version of WSO2 Identity Server when it is released. For more information on updating WSO2 Identity Server using WUM, see Getting Started with WUM in the WSO2 Administration Guide.

 WS-Trust Security Token Service Configuration

WSO2 Identity Server uses the security token service (STS) as the WS-Trust implementation. The STS is capable of issuing SAML 1.1 and 2.0 security tokens and has a SOAP/XML API for token issuance. This API can be secured with the UserNameToken or with any other WS-Security mechanism as explained below.

Securing the Security Token Service

According to the Trust Brokering model defined in the WS-Trust specification, the users should authenticate themselves to the STS before obtaining a token. STS may use this authentication information when constructing the security token. For example, STS may populate the required claims based on the user name provided by the subject. Therefore, the STS service needs to be secured.

STS is configured under the Resident Identity Provider section of the WSO2 Identity Server Management ConsoleFollow the instructions below to secure the Security Token Service by logging into the management console.

  1. Log in as an admin to access the management console.
  2. Configure the Resident Identity Provider. See here for more detailed information on how to do this.
  3. In the Resident Identity Provider page, expand the Inbound Authentication Configuration section along with the Security Token Service Configuration section.
  4. Click Apply Security Policy.
  5. Select Yes in the Enable Security? dropdown and select a pre-configured security scenario according to your requirements. In this case, we will use UsernameToken under the Basic Scenarios section. 

    You can find further details about security policy scenarios from the view scenario option.

  6. Click Next.

    Next steps may vary as per the security scenario that you have chosen under point (5) above. Below is for UsernameToken scenario.

  7. Select ALL-USER-STORE-DOMAINS from the drop-down.
  8. In the resulting page, select the role you created to grant permission to access secured service. In this example, the admin role is used. Next, click Finish.

    The Select Domain drop-down lists many domains. The listed User Groups can vary depending on the domain selected.

  9. Click Ok on the confirmation dialog window that appears.
  10. Click Update to complete the process.

Now STS is configured and secured with a username and password. Only users with the Admin role can consume the service.

The next step is to add a service provider to consume the STS.

Adding a service provider for the STS client

Do the following steps if you are using a Holder of Key subject confirmation method. See Configuring STS for Obtaining Tokens with Holder-Of-Key Subject Confirmation for more information.

The Subject confirmation methods define how a relying party (RP), which is the end service can make sure a particular security token issued by an STS is brought by the legitimate subject. If this is not done, a third party can take the token from the wire and send any request it wants including that token. The RP trusts that illegitimate party.

  1. See Configuring a Service Provider for details on adding a service provider. 
  2. Expand the Inbound Authentication Configuration section and the WS-Trust Security Token Service Configuration section. Click Configure.
  3. In the resulting screen, enter the trusted relying party's endpoint address that is the endpoint address of the Security Token Service. For more information, see Broker Trust Relationship with WSO2 Identity Server and upload the public certificate of the trusted relying party. 

    You need to add the certificate of the relying party to the truststore. For more information on how to create the certificate and add it to the truststore, see here.

    The endpoint must be used as the service URL to which the token gets delivered by the STS client. Then select the public certificate imported. Tokens issued are encrypted using the public certificate of the trusted relying party. Therefore, the consumer who obtains this token, to invoke the RP service, won't be able to see the token. 

  4. Click Update to save the changes made to the service provider.
