I set up a new CUPS server, which works perfectly for all Linux machines. On the same server I installed a samba member server to allow for printing from Windows machines. Initial installation worked fine and I could print test pages from all windows systems. Today I wanted to print from an XP machine (non-member) and it failed with the error given in the subject. Printing from a Win7 client (member) however works. The samba server is 4.1.17-Debian (Jessie current) This is the config as seen by testparm: [global] workgroup = AD realm = AD.MICROSULT.DE security = ADS kerberos method = system keytab local master = No domain master = No winbind enum users = Yes winbind enum groups = Yes winbind use default domain = Yes winbind nss info = rfc2307 winbind refresh tickets = Yes winbind normalize names = Yes idmap config AD: schema_mode = rfc2307 idmap config AD: backend = ad idmap config AD: range = 1001 - 29999 idmap config * : backend = tdb [printers] path = /var/spool/samba printable = Yes print ok = Yes browseable = No [print$] comment = Printer Drivers path = /srv/samba/Printer_drivers write list = mgr, Administrator create mask = 0664 directory mask = 0775 [P6026cdn] path = /var/spool/samba/ printable = Yes print ok = Yes printer name = P6026CDN I've seen comments for older versions of samba with the recommendation to add "writeable=yes" to [printers]. However, if I do that and run testparm, the option does not show. Can someone help with my confusion? Regards, - lars.
