PI52613: SAML SP-INITIATED WEB SSO REQUIRES DYNACACHE OR FRONTEND AFFINITY

Fixes are available

APAR status

Closed as program error.

Error description

SAML SP-initiated Web SSO requires that an Identity Provider
server send its SAMLResponse back to the entity which initially
solicited it via a SAMLRequest.

In a cluster environment, if you are unable to use session
affinity or dynacache, SP-initiated SAML Web SSO will not work.

Local fix

enable dynacache or session affinity in the environment

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server and SAML Web SSO                     *
****************************************************************
* PROBLEM DESCRIPTION: SAML SP-initiated Web SSO may not       *
*                      work properly in a cluster environment  *
****************************************************************
* RECOMMENDATION:  Install a fix pack that contains this       *
*                  APAR.                                       *
****************************************************************
Since SAML SP-initiated Web Single Sign-on (SSO) depends on
the SAMLResponse from the identity provider (IdP) being sent
back to the same server that sent the SAMLRequest, it may not
work properly in a cluster environment.

Problem conclusion

SAML SP-initiated Web SSO requires that an Identity Provider
server send its SAMLResponse back to the entity which initially
solicited it via a SAMLRequest. In a cluster environment,
when the IdP sends the SAMLResponse, without session
affinitiy, the individual cluster member that receives the
response is indeterminate. If the cluster member  that
receives the response is not the member that sent the
SAMLRequest, the login process will fail.

The SAML Web SSO TAI is updated so that, in a Network
Deployment environment, when one cluster member sends a
SAMLRequest to an IdP, any cluster member can process the
SAMLResponse and complete the login request.

The fix for this APAR is currently targeted for inclusion in
fix packs 7.0.0.43, 8.0.0.13, and 8.5.5.10.  Please refer to
