List domain groups:
net groupmap list
Adding domain group:
smbldap-groupadd -a interchange
Adding user to domain group:
smbldap-groupmod -m racke interchange
Please restart Samba after adding domain groups or adding user to domain groups.
This isn't possible with smbfs (see Samba mailinglist). The solution is to mount with cifs like that:
//server/share /local/dir cifs credentials=/etc/local/creds,ip=192.168.0.200
