    ****************************************************************
    The OpenID Connect (OIDC) Relying Party (RP) Trust Association
    Interceptor (TAI) does not read the user information from the
    UserInfo endpoint on the OpenID Connect Provider (OP).
    Information about the UserInfo endpoint can be found here:
    http://openid.net/specs/openid-connect-core-
    1_0.html#UserInfoReq
    uest
    If an application needs access to the user information that is
    available on the UserInfo endpoint, they must have an
    alternate method for retrieving the information.
    

Problem conclusion

  • The OIDC RP is updated to allow an administor to configure a
    UserInfo endpoint.  If a UserInfo endpoint is configured and
    an access token is available, the RP will acquire and store
    the user information that is returned from the UserInfo
    endpoint invocation as described below.
    
    The OIDC RP TAI is updated to add the following custom
    property to support the UserInfo endpoint on the OP:
    
    provider_<id>.userinfoEndpointUrl
    
    This property is optional and does not have a default value.
    
    The provider_<id>.userinfoEndpointUrl property specifies the
    URL for the UserInfo endpoint on the OP.  The login process
    will not fail if an error occurs while making a call to the
    UserInfo endpoint.  The response received from the UserInfo
    endpoint is be placed on the WebSphere Subject with the
    [user_info] key.
    .
    If the call to the endpoint is successful, the value for the
    [user_info] entry on the Subject is the JSON string.
    Otherwise, the value contains information about the error,
    such as the response code and error message from the OP or the
    exception text.
    .
    The UserInfo endpoint is invoked each time the OIDC RP
    receives an access token from the OP.
    
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.5.5.14 and 9.0.0.8.  Please refer to the
