FIX: Soft lockout does not apply if Outlook Anywhere uses KCD for SSO to Exchange Server

View products that this article applies to.

Symptoms

You configure Microsoft Forefront Unified Access Gateway (UAG) 2010 to perform a soft lockout on a user after several failed authentication tries. If you also configure Microsoft Outlook Anywhere to use Kerberos Constrained Delegation (KCD) for Single Sign-On (SSO) access to Microsoft Exchange Server, you find that the soft lockout process does not apply.

In this configuration, Outlook authenticates to UAG by using NTLM authentication.

Cause

This problem occurs because the "Integrated Windows Authentication" handler in UAG does not check the account lockout status correctly.
