Hi, I upgraded our print server from 2.2.8 to 3.0.1 and have had trouble subsequently. I can't add drivers with cupsaddsmb and have been trying to investigate the root cause. As far as I can tell, the appropriate administrative users aren't working correctly. From a Windows workstation, logged in as the domain admin, I expect to be able to change printer settings (e.g. Location or Comment fields) or create files/folders in Print$ but get "Access is denied". I've been unable to add drivers for printers for weeks and will have to revert to a Windows server if I can't get this sorted out. I'm using RH9.0 and winbind. net groupmap list lists Domain Admins (S-1-5-21-2145034631-2117181475-4186310193-512) -> ntadmins (Which looks right to me). The relevant bits in smb.conf are: [global] printer admin = @ntadmins, administrator [printers] printer admin = @ntadmins, administrator [print$] write list = @ntadmins, administrator Please help, I'm at the end of my tether! Thanks, Leon...
