Hi I don't exactly know if this is a samba/winbind issue or a cups issue. I hope it is OK to ask anyway. I set up a Samba 4.1.2 Server on a Ubuntu 13.10, 64Bit mashine. So far most things run quite well. Now I test sharing printers via cups. I use IPP for this. Works well from Windows 7 mashines so far. Next thing is to set allowed users for some printers. If I set just a username it works. If I try to set a group no one can print. If I set just an allowed user a line Allow username I tried adding groups with Allow @Groupname and Allow @Domainname\Groupname Neither worked. Does anybody have an idea what might be wrong here. Maybe cups has some problems with winbind? Thanks for reading Bernd
