Problem summary

****************************************************************
* USERS AFFECTED:  IBM WebSphere Application Server            *
*                  administrators of SAML Web Single Sign-On   *
****************************************************************
* PROBLEM DESCRIPTION: IdP-initiated SAML SSO fails when no    *
*                      RelayState in SAMLResponse              *
****************************************************************
* RECOMMENDATION:  Install a interim fix or fix pack that      *
*                  contains this APAR.                         *
****************************************************************
In the SAML Web Single Sign-On (SSO) Trust Association
Interceptor (TAI), if a SAMLResponse that does not contain a
RelayState parameter is received from an identity provider
(IdP), the authentication will fail.
This error only occurs in WebSphere Application Server v8.0,
fixpack 8.0.0.11 and v8.5, fixpack 8.5.5.7.  This error does
not occur in WebSphere Application Server v7.

Problem conclusion

The SAML Web SSO TAI is updated so that an error does not
occur when a SAMLResponse that does not contain a RelayState
is received from an IdP.

The fix for this APAR is currently targeted for inclusion in
fix packs 8.0.0.12 and 8.5.5.8.  Please refer to the
Recommended Updates page for delivery information:
