This can be done only once you have installed the WSO2 Identity Server 5.0.0 along with the Service Pack. The authentication endpoint is the authentication URL used in authentication requests. The following sections discuss methods of customizing this endpoint for various scenarios.

Controlling the request parameters going to the authentication endpoint

Additional request parameters can be added and customized for the request sent to the authentication endpoint. To customize this, uncomment the following configurations in the <IS_HOME>/repository/conf/security/application-authentication.xml file, under the ApplicationAuthentication element (which is the root element).

<!--AuthenticationEndpointQueryParams action="exclude"-->
<!--AuthenticationEndpointQueryParam name="username"/-->
<!--AuthenticationEndpointQueryParam name="password"/-->
<!--/AuthenticationEndpointQueryParams-->

Note: In the above configuration, username and password are just given as examples. You can configure any query parameter here for your request and customize it according to your specifications.

Loading tenants into the dropdown in the login page of the authentication endpoint web application

This section is useful in scenarios where there are multiple tenants used where users can login to web applications with their credentials for their specified tenants. Doing the following configurations will enable you to load all the available active tenants into a dropdown list in the login page of the web application that the authentication endpoint points to.

  1. Edit the <IS_HOME>/repository/conf/tomcat/catalina-server.xml file and set the clientAuth attribute in the Connector tag to “want” as shown below. This is done to disable the certificate authentication on certain occasions (like when working on mobile apps). This makes two-way SSL authentication optional.

    clientAuth="want"
  2. Copy the org.wso2.carbon.identity.authenticator.mutualssl-4.2.0.jar file in the <IS_SP_HOME>/resources/dropins folder to the <IS_HOME>/repository/components/dropins/ directory.
  3. Copy the following into the <IS_HOME>/repository/conf/security/authenticators.xml file under the Authenticators tag.

    <!-- Authenticator Configurations for MutualSSLAuthenticator-->
    <Authenticator name="MutualSSLAuthenticator" disabled="false">
        <Priority>5</Priority>
        <Config>
            <Parameter name="UsernameHeader">UserName</Parameter>
            <Parameter name="WhiteListEnabled">false</Parameter>
            <Parameter name="WhiteList"/>
        </Config>
    </Authenticator>
  4. If the SAML2SSOAuthenticator is enabled (disabled="false") in the <IS_HOME>/repository/conf/security/authenticators.xml file, set its priority to 0. Otherwise ignore this step.

    <Authenticator name="SAML2SSOAuthenticator" disabled="false">
    	<Priority>0</Priority>
    	...
    </Authenticator>
  5. Add the following configuration into the <IS_HOME>/repository/conf/security/application-authentication.xml file under the ApplicationAuthentication tag.

    <TenantDomainDropDownEnabled>true</TenantDomainDropDownEnabled>
    <TenantDataListenerURLs>
    	<TenantDataListenerURL>
    		/authenticationendpoint/tenantlistrefresher.do
    	</TenantDataListenerURL>
    </TenantDataListenerURLs>

    When configuring the TenantDataListenerURL tag, note the following.

    • In a clustered setup that has multiple authentication endpoint web applications hosted, list all of them under the TenantDataListenerURL tag.

    • For authentication endpoint web applications hosted outside the WSO2 Identity Server or in other nodes of a cluster, add the absolute URL within the TenantDataListenerURL tag.

  6. Restart the server using one of the following commands.

    • Windowswso2server.bat

    • Linux/Unixsh wso2server.sh

  7. Once the server is restarted, the authenticationendpoint.war file is deployed. The <IS_HOME>/repository/deployment/server/webapps/authenticationendpoint/WEB-INF/classes/TenantConfig.properties file has to be changed with the required values for properties. The following are the default values for the properties to be used in this file.

    tenantListEnabled=false
    mutual.ssl.username=admin
    client.keyStore=./repository/resources/security/wso2carbon.jks
    client.keyStore.password=wso2carbon
    client.trustStore=./repository/resources/security/client-truststore.jks
    client.trustStore.password=wso2carbon
    identity.server.host=localhost
    identity.server.port=9443
    username.header=UserName

    Do the following updates to this configuration.

    1. Set tenantListEnabled to true in order to enable the tenants to display as a list.
    2. For the mutual.ssl.username property, set the username that is to be used for mutual SSL authentication. This user needs to have permission to list down tenants. You can add a new username here provided that you create a user with that username and grant the following permissions to the role of the user.

      Super Admin Permissions > Manage > Monitor > Tenants > List

    3. Set the Identity Server host and the port in identity.server.host and identity.server.port properties.
    4. Paths for client keystore and truststore can be relative paths or absolute paths. The default paths point to the keystore and truststore of the Identity Server itself. A new keystore can be created and used for the client if necessary, however, you must set the passwords for client.keyStore.password and client.trustStore.password appropriately.

  8. For mutual SSL authentication, the public certificate of the Identity Server has to be imported to the truststore of the client and the public certificate of the client has to be imported to the client-truststore of Identity Server.

    Sample commands

    The following two commands are examples if you are using the keystore and client-truststore of the Identity Server itself for the client. This is executed from the <IS_HOME>/repository/resources/security directory.

    keytool -export -alias wso2carbon -file carbon_public2.crt -keystore wso2carbon.jks -storepass wso2carbon
    keytool -import -trustcacerts -alias carbon -file carbon_public2.crt -keystore client-truststore.jks -storepass wso2carbon

Removing the tenant list from the login page

If it is required to remove the tenant domain dropdown list in SSO Login page, follow the steps below.

  1. Shutdown the server if it is already started.
  2. Set the property tenantListEnabled=false in the <IS_HOME>/repository/deployment/server/webapps/authenticationendpoint/WEB-INF/classes/TenantConfig.properties file.
  3. Set TenantDomainDropDownEnabled parameter to false in the <IS_HOME>/repository/conf/security/application-authentication.xml file.

    <TenantDomainDropDownEnabled>false</TenantDomainDropDownEnabled>
  4. If the MutualSSLAuthenticator is only used for the purpose of listing tenant domains in the drop down, disable it in the <IS_HOME>/repository/conf/security/authenticators.xml file.

    <Authenticator name="MutualSSLAuthenticator" disabled="true">
  5. Restart the server
