****************************************************************
* USERS AFFECTED:  All users of WebSphere Application Server   *
****************************************************************
* PROBLEM DESCRIPTION: When a custom Trust Association         *
*                      Interceptor is enabled, user            *
*                      authentication may fail.                *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
On WebSphere Application Server Version 7.0, if
com.ibm.wsspi.security.cred.userId attribute exists in the
custom properties, wsMapDefaultInboundLoginModule.class
recreates a WSCredential based on the value of the attribute
to support mapping user id for Kerberos authentication.
However, since LTPAToken is not generated upon creating a new
WSCredential, A Subject object which contains the newly
created WSCredential won't be treated as a valid Subject.

Problem conclusion

With this fix, LTPAToken is generated when new WSCredential is
generated by an attribute of com.ibm.wsspi.security.cred.userId.

The fix for this APAR is currently targeted for inclusion in
fixpack 7.0.0.5.  Please refer to the Recommended Updates
