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.

    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.
