Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server and OpenID Connect                   *
    ****************************************************************
    * PROBLEM DESCRIPTION: The OIDC TAI does not support the       *
    *                      RS512 signature algorithm.              *
    ****************************************************************
    * RECOMMENDATION:  Install a fix pack or interim fix that      *
    *                  contains this APAR.                         *
    ****************************************************************
    The OpenID Connect (OIDC) Relying Party (RP) Trust Association
    Interceptor (TAI) does not support the RS512 signature
    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
