Single sign-on is a key feature of the WSO2 Identity Server that enables users to access multiple applications using the same set of credentials. Additionally, the user can access all these applications without having to log into each application individually. For instance, if users log into application A, they would automatically have access to application B as well for the duration of that session without having to re-enter their credentials.
The profile specification for Security Assertion Markup Language 2.0 (SAML 2.0) defines single sign-on based on a web browser. This topic provides instructions on how to use the sample available in the WSO2 Identity Server to configure SSO using SAML 2.0 with a sample service provider.
See the following topics for instructions on how to configure the sample with the WSO2 Identity Server.
Before you begin!
- To ensure you get the full understanding of this tutorial, the sample travelocity applciation is used in this use case. Therefore, make sure to download the samples before you begin.
- Download Tomcat 7.x. The samples are written on Servlet 3.0. Therefore, they need to be deployed on Tomcat 7.x.
- Install Apache Maven. For more information, see Installation Prerequisites.
Configuring the SSO web application

localhost. Cookies are required when working with SSO. Therefore, to ensure that the SSO capabilities work as expected in this tutorial, you need to configure the
etc/host file as explained in this step.
etc/host file is a read-only file. Therefore, you won't be able to edit it by opening the file via a text editor. To avoid this, edit the file using the terminal commands.
For example, use the following command if you are working on a Mac/Linux environment.

Configuring the service provider
The next step is to configure travelocity.com as the service provider. The following steps instruct you on how to do this.
- Start the Identity Server and access the management console using
- Log in to the Identity Server using default administrator credentials (the username and password are both
admin). If you need to create the service provider in a tenant space, you need to login with tenants user.
- Select the Main menu that is on the left side of the management console and click Add under Service Provider.
travelocity.comas the value for the Service Provider Name filed and click Register.
- Expand the Inbound Authentication Configuration section and then expand SAML2 Web SSO Configuration.
- Select Manual Configuration.
Register the new service provider by providing the following values. See the table below for more information about the fields in this form.
Note: To add the correct tenant domain with the username as the subject identifier in tenant mode,
Expand the Local & Outbound Authentication Configuration section and do the following.
- Select Use tenant domain in local subject identifier to append the tenant domain to the local subject identifier.
- Select Use user store domain in local subject identifier to append the user store domain that the user resides in the local subject identifier.
For super tenant mode, this step is not required and the two options mentioned above should remain disabled by default.
- Click Update to register.
- Configure claims for the service provider. To do this, do the following. For more information on configuring this, see Configuring Claims for a Service Provider.
- Expand the Claim Configuration section in the service provider form.
- You can select the claims that must be sent to the service provider. If you just want to send them as claim URIs, select Use Local Claim Dialect.
- Alternatively, if you want to define new claim URIs for the attributes that are sent, you can define any values for them and map these values with the claim URIs local to WSO2.
For example, you want to set the email address of the user as
http://wso2.org/claims/emailaddress. To specify this, select the Define Custom Claim Dialect option and click Add Claim URI. Enter the Service Provider Claim URIs and select the matching local claim from the dropdown. You can also mark them as a Requested Claim or a Mandatory Claim. For more information, see Configuring Claims for a Service Provider.
- Configure outbound authentication as Default authentication type. This specifies that the identity provider authenticates the users with the username/password by validating with the identity provider's user store.
- After providing the above information, click Register.
After successfully registering the service provider, log out from management console. The next step is to run the sample.
Running the sample
http://wso2is.local:8080/travelocity.com. You are directed to the following page:
- Since you need to use SAML2 for this sample, click the first link, i.e., Click here to login with SAML from Identity Server. You are redirected to the Identity Server for authentication.
- Enter the default admin credentials (admin/admin).
- Now you are logged in and you can see the home page of the travelocity.com app.
If you need to view the SAML request and response, please add the following debug log to the
log4j.propertiesfile found inside
- Since single log out is enabled, if you click the logout button in the travelocity.com home page, you will successfully log out.
