I have a samba server called RUT that joined the nt-domain INFO with a PCD named ARCH. The users on info can connect to RUT perfectly. ARCH trusts the nt-domain-groups W3_BD and W3_BT of the nt-domain BYGGDOK on a PDC named BYGGDOK, but those users are denied by RUT. (they can connect to other nt-servers in the nt-domain INFO) I tried: domain groups = W3_BD W3_BT which did me no good. (Cant find any documentation on that option) How to configure samba to do this? RUT only provides SHARES, no printers and no login. The UNIX-users are not allowed to connect to the samba-server (thus no smbpasswd-file). The system is RedHat 5.2 and samba is 2.0.2. Here is the current smb.config. I tried both with and without the options marked by a * and the server was restarted every time. # Samba config file created using SWAT # from localhost (127.0.0.1) # Date: 1999/02/23 11:26:31 # Global parameters workgroup = INFO netbios name = RUT server string = Byggdoks testsambaserver fr webben security = DOMAIN encrypt passwords = Yes password server = ARCH BYGGSERV // I tried to add BYGGSERV (didnt do it) log file = /var/log/samba/log.%m max log size = 50 socket options = TCP_NODELAY * domain groups = W3_BD W3_BT dns proxy = No * wins server = 193.10.7.19 * domain logons = no * hosts allow = 193.10.7. 127.0.0.1 log level = 10 [homes] comment = Home Directories read only = No browseable = No [byggdok] path = /home/httpd/byggdok read only = No [byggtorg] path = /home/httpd/byggtorg read only = No /Roos
