With respect to Mr. Allison, figuring out what changed isn't always 
simple. Sometimes it can be something that is only peripherally 
connected to Samba, such as a DNS server upgrade.

In general, the Unix permissions need to be permissive enough to allow 
Samba to control the access. You may also want to check that the users 
are actually logging on. Try checking the Samba logs to see if there is 
a problem being reported. If that doesn't work, set the Samba loglevel 
to 10, restart Samba and try again.
