Product Defect 806634

This issue is being caused by an Authentication Services defect. The issue occurs when an application calls pam with pam_setcred(handle,PAM_DELETE_CRED), vas returns a failure when it shouldn't. The call is essentially a cleanup call after everything else is done which is why the authentication don't fail.
