Hi, I have a problem printing on a RHEL3 server running samba-3.0.9-1.3E.1. The server is configured to authenticates users using a nearby Windows 2000 Active Directory server. Windows users are authenticated to shared drives just fine, but printing from Windows clients is proving impossible. Occasionally I can hit a configuration that allows me to add a printer on my PC using the Add Printer wizard (usually by adding 'disable spoolss = yes' to smb.conf). But if I try to connect to the printer share from my Windows PC and print a test page, the test page fails to print and Windows asks to launch the troubleshooter. Looking in the Samba logs I see entries like this: [2005/01/13 12:24:46, 3] lib/util_seaccess.c:se_access_check(251) [2005/01/13 12:24:46, 3] lib/util_seaccess.c:se_access_check(252) se_access_check: user sid is S-1-5-21-1214440339-1580818891-1202660629-2125 se_access_check: also S-1-5-21-1214440339-1580818891-1202660629-513 se_access_check: also S-1-1-0 se_access_check: also S-1-5-2 se_access_check: also S-1-5-11 se_access_check: also S-1-5-21-1214440339-1580818891-1202660629-2183 se_access_check: also S-1-5-21-1214440339-1580818891-1202660629-2181 se_access_check: also S-1-5-21-1214440339-1580818891-1202660629-2184 se_access_check: also S-1-5-21-1214440339-1580818891-1202660629-2185 se_access_check: also S-1-5-21-1214440339-1580818891-1202660629-2188 se_access_check: also S-1-5-21-1214440339-1580818891-1202660629-2186 se_access_check: also S-1-5-21-1214440339-1580818891-1202660629-2187 se_access_check: also S-1-5-21-15958514-230334199-2340646718-3015 se_access_check: also S-1-5-21-15958514-230334199-2340646718-3017 se_access_check: also S-1-5-21-15958514-230334199-2340646718-3019 se_access_check: also S-1-5-21-15958514-230334199-2340646718-3023 se_access_check: also S-1-5-21-15958514-230334199-2340646718-3025 se_access_check: also S-1-5-21-15958514-230334199-2340646718-3027 se_access_check: also S-1-5-21-15958514-230334199-2340646718-3033 se_access_check: also S-1-5-21-15958514-230334199-2340646718-3035 se_access_check: also S-1-5-21-15958514-230334199-2340646718-5047 [2005/01/13 12:24:46, 3] printing/printing.c:print_job_start(2224) print_job_start: job start denied by security descriptor (Those are my, valid SIDs; I see the same SIDs displayed when connecting to a shared drive, followed in the samba log by messages indicating that my SIDs have been mapped correctly to a Unix user account.) I'm completely stumped about the security descriptor entry: what security descriptor? One on the AD server? The relevant pieces of the smb.conf are: [global] server string = Bertha SAMBA server netbios name = bertha client schannel = auto server schannel = auto client signing = Auto server signing = Auto client use spnego = yes map to guest = bad user winbind enum users = yes winbind enum groups = yes winbind use default domain = yes password server = 192.168.1.3 ldap ssl = on idmap uid = 1000-20000 idmap gid = 1000-20000 name resolve order = wins bcast disable spoolss = yes printcap name = cups load printers = yes printing = cups cups options = raw guest account = nobody log file = /var/log/samba/%m.log max log size = 500 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 local master = no domain master = no preferred master = no security = ADS wins server = 192.168.1.8 wins proxy = yes dns proxy = no [printers] comment = All Printers path = /var/spool/samba create mode = 0600 browseable = no public = yes printable = yes guest ok = yes writable = no use client driver = yes This is driving me crazy. I've searched on Google and seen a lot of discussion in the past related to adding 'use client driver = yes' (which I have) and setting the correct permissions on /var/spool/samba (done). This problem seems to be directly related to how SAMBA+AD detemermine user permissions, but beyond that I have no idea what's really wrong or how to fix it. Any help appreciated, -Adam
