[Samba] Samba 4 & Thunderbird Mail Client

[Gaiseric Vandal]

Can you turn OFF extended ACLs on the file share used for the profiles 
?   I ran into a weird issue years ago with Office 2013 documents on 
samba shares with extended ACLs.  Every 5th save the document would get 
deleted.  The problem was that every 5th save should have involved 
writing a new file, deleting the old file, then renaming the new file to 
the original name.  The Windows ACL model doesn't always match up 
perfectly with the Unix or Linux ACL model.
