From d2465b17300168c37230de34f71e99d5b02d306d Mon Sep 17 00:00:00 2001 From: Jeremy Allison Date: Tue, 5 Sep 2006 05:28:31 +0000 Subject: r18062: Fix to ensure the name used by pam matches the name that will be returned by winbindd. This (should) fix the bug where the user logs in with DOMAIN\user but winbindd returns only "user" for the username due to 'winbind use default domain' being set. Jeremy.
