Error description
The OAuth token introspection endpoint is expected to include the issuer of a provided access token in the data that it returns. However if an OpenID Connect provider is configured to use the OAuth provider that is performing the introspection, and that OpenID Connect provider has the issuerIdentifier attribute configured, the token introspection endpoint does not return the value of the issuerIdentifier attribute as the issuer of the token.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Liberty - OAuth and OpenID Connect * * Provider * **************************************************************** * PROBLEM DESCRIPTION: OAuth introspect endpoint does not * * return correct issuer if OpenID Connect * * provider configures issuerIdentifier * **************************************************************** * RECOMMENDATION: * **************************************************************** The OAuth token introspection endpoint is expected to include the issuer of a provided access token in the data that it returns. However if an OpenID Connect provider is configured to use the OAuth provider that is performing the introspection, and that OpenID Connect provider has the issuerIdentifier attribute configured, the token introspection endpoint does not return the value of the issuerIdentifier attribute as the issuer of the token.
Problem conclusion
The OAuth token introspection endpoint is updated to read the issuerIdentifier configuration attribute from an associated OpenID Connect provider, if one is configured. If a valid issuerIdentifier is configured, that value is used for the "iss" value that is returned in the token introspection endpoint response. The fix for this APAR is currently targeted for inclusion in fix pack 19.0.0.2.
