[Samba] Quota shows S-XXX instead of actual names

[Ephi Dror]

Hi everyone,
 
I am wondering why do I see S-XXX numbers instead of actual names when
viewing and setting quota from windows.
 
My server is configured as a stand alone in which I use pdbedit to add
bunch of users.
 
However,  when I look at properties-> security, names are coming up
correct (not as S-XXX numbers)
 
Any idea why.
 
Your help is highly appreciated.
 
Cheers,
Ephi
