Did some single sign-on tweaks to my CentOS 6.5 box that calls BackupPC home. Wondering if I changed something within smb.conf that might have screwed things up for this program. Every windows hosts now fails to back-up and shows a similar message to what you see below.

Any ideas on places to look? Thanks!
