    * PROBLEM DESCRIPTION: The OIDC RP TAI can not send the        *
    *                      nonce parameter on the login request    *
    *                      to the OP.                              *

    * RECOMMENDATION:  Install a fix pack or interim fix that      *
    *                  contains this APAR.                         *
    ****************************************************************
    The WebSphere tradtional OpenID Connect Relying Party cannot
    include a nonce parameter on the initial login request to an
    OpenID connect provider.
    

Problem conclusion

  • The OIDC RP TAI is updated to allow the nonce parameter to be
    included on the initial authentication request to the OP.
    
    The following OIDC TAI custom property is added:
    
    provider_.nonceEnabled
    
    Valid values for this property are true and false (default).
    
    When this property is set to true, a nonce parameter is sent
    to the OpenID Connect provider on the initial authentication
    request.
    
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.17 and 9.0.5.3.  Please refer to the Recommended
