algorithm.

    



Problem conclusion


    

  • The OIDC TAI is updated to support the RS512 signature
algorithm.  RS512 is added to the supported values for the
provider.<id>.signatureAlgorithm OIDC TAI property.

The fix for this APAR is targeted for inclusion in fix pack
8.5.5.18 or 9.0.5.4.  For more information, see
