Hi Doc
First yuo update your samba to last 2.2.8... from samba binary ftp for
Second your problem with share level security.
When your users Joe not logout when end work and user Mary then work with PC
no way to protect your system!
First yuo learn about login logout feature of Windows network an afther this
you set samba to user level security
this is best choice for all.
If you dont need domain then config user security is very simple set this on
smb.conf and restart samba
create user joe and mary on redhat
then run smbpasswd -a joe and repeat mary with set pass.
And on windows login with this settings and logout afther end work.
