2cent note-- RE: [Samba] Access denied, unable to connect to prin ter
We had a similar problem here, different but perhaps not entirely unique if someone else happens to make the same mistake. We give kudos to the samba logging. =) We have a linux samba print server with cups as a member server of an nt4 domain. The win98 users could print fine, win 2k could not - but that wasn't the problem, though only these systems had an "access denied" error message for the network printers. In the samba global config, we had "admin users = root,@NT4dom+adminusers" so these users were being translated to "root" while we also had "valid users = @NT4dom+domainusers" in the global samba config as well (to prevent share/printer enumeration by nondomain users)... so, this prevented our NT4dom+adminusers group from printing... as "root" was not in the "valid users" field. So we added 'root' to the "valid users = " line and it works again. hth someone else out there. peace Brian and Brandon |-----Original Message----- |From: Ryan Novosielski [mailto:novosirj@umdnj.edu] |Sent: Tuesday, May 20, 2003 9:40 AM |To: Samba Mailing List |Subject: Re: [Samba] Access denied, unable to connect to printer | | |I have the exact same problem.
