[Samba] Roaming Profiles not updating at logoff/shutdown

[Rob Sell]

I administer a medium size samba domain and all was working well until I
went in the other day and looked at the age of peoples profiles, there were
3 users who hadn't saved their roaming profile to the server for weeks. So I
went and asked if they have been shutting down properly checked the
date/time compared to the servers, made sure their profile was still set to
roaming, etc.

No luck. What am I missing here? Is there a way to force their profiles to
update? Any idea why profiles would stop getting copied to the server?
