Fixes are available

APAR status

Closed as program error.

Error description

When using SAML Web SSO, it is an error if there is no NameID
element as a child of the Subject element.  An exception is
thrown, but there is no indication why.  When running a trace,
this is all you get:

[2/5/14 10:34:13:861 CST] 00000038 ACSTrustAssoc 3
createResult with Exception:null
...
[2/5/14 10:34:13:872 CST] 00000038 ACSTrustAssoc 3
SAMLResponse could not be verified.null

****************************************************************
When using SAML Web Single Sign On (SSO), the SAML assertion's
Subject element must have a NameID child element.  If it does
not, an error will occur.  When this condition occurs at
runtime, an exception is thrown, but there is no indication
why.  When running a trace, this is all you get:
[2/5/14 10:34:13:861 CST] 00000038 ACSTrustAssoc 3
createResult with Exception:null
...
[2/5/14 10:34:13:872 CST] 00000038 ACSTrustAssoc 3
SAMLResponse could not be verified.null
.NET does not put the NameID element in the Subject by
default.  Because of this, this seems to be a relatively
common error.  Better information should be given about the
nature of this error.

Problem conclusion

The SAML Web SSO runtime is updated to emit exceptions that
show the nature of the error when the NameID element is
missing from the Subject.  For example:

CWSML7010E: The [NameID] sub-element of the [Subject]
element in the SAML assertion element is missing or empty.

CWSML7006E: The [NameQualifier] attribute on the [NameID]
element is missing or empty.  This condition is not allowed.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.33, 8.0.0.9, and 8.5.5.3.  Please refer to the
