Hi, I am trying to setup a Samba server as a Primary Domain Controller, I have added some user accounts and created some shares and I can access them from a win XP client. Now I would like the Samba server to be the PDC. I like to join the domain, however when I set the domain in XP I have to enter a username and password for domain binding. The message I recieve is: The following error occured attempting to join the domain"domainxx". The username could not be found. In the samba log files I find the following error messages every time I try to connect: [2008/02/21 09:29:45, 0] auth/auth_util.c:create_builtin_administrators(785) create_builtin_administrators: Failed to create Administrators [2008/02/21 09:29:45, 0] auth/auth_util.c:create_builtin_users(751) create_builtin_users: Failed to create Users Please also find my smb.conf file here (part of it): log file = /var/log/samba/log.%m load printers = No ldap ssl = no passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessfully* . include = /etc/samba/dhcp.conf socket options = TCP_NODELAY obey pam restrictions = Yes logon drive = C: force group = all deadtime = 15 domain master = Yes winbind enable local accounts = no passdb backend = tdbsam passwd program = /usr/bin/passwd %u wins support = true allow hosts = 10.64.1.0/255.255.255.0, 10.32.2.0/255.255.255.0, 10.64.7.0/255.255.255.0 dns proxy = No domain admin users = root oplocks = no netbios name = PDC01 server string = %h server writeable = yes logon script = %U.cmd remote announce = 10.32.2.255/DOMAINXX workgroup = domainxx force user = smbguest os level = 32 add user script = /usr/sbin/useradd -d /dev/null -g 300 -c "Machine Account" -s /bin/false -M %u update encrypted = Yes syslog = 0 panic action = /usr/share/samba/panic-action %d max log size = 1000 domain logons = Yes security = user Anyone any clue? -- View this message in context: http://www.nabble.com/auth-auth_util.c%3Acreate_builtin_users%28751%29-tp15607220p15607220.html Sent from the Samba - General mailing list archive at Nabble.com.
