[Samba] multiple user folders showing up

[phwashington at comcast.net]

I have set up my samba with winbind and it appears to be working fine.  Altered the pam.d/system-auth file and it is creating the user directories.  The issue I am running into is that if "biguser" logs in and goes to the server and then logs out of the W2K client and then user "david" logs in on the same client and goes to the server he sees shared directories or appears to see shared directories [biguser] and [david].   From my testing though it appears that he is actually only seeing david, because if I go to the share [biguser] I can create a file or directory and it appears in the share [david].  When I look in /home/user/david and /home/user/biguser though the files are only created in /home/user/david.  If biguser then logs into the same client then the same thing appears to happen.
I'm concerned that this may freak out some of the users and make them think that the server is unsecure and that users can access other users home directories.
