[Samba] upgrading from 3.0.13 to 3.0.23

[Jean-Baptiste Estival]

Hi all

I just downloaded the latest sable rlease (3.0.23b). I compiled it and 
installed it without any problems.
When I restart servers, shares configured like this :
[xdavid]
        read list = user
        browseable = no
        path = /home/users/xdavid
        write list = xdavid
        only user = yes
        user = xdavid

works fine, but these shares (using goups names) doesn't work:
[utilisateurs]
        write list = @root      
        writeable = yes
        user = @utilisateurs, at root
        path = /home/users
        only user = yes
        read list = @utilisateurs, at root

groups and users are local to the samba server (running under Linux FC1).

I use webmin to configure samba.

Does anyone has an idea ?

thanks
