I know this problem has been addressed before on this list, but I think I'm running into something new here. I have a couple of debian boxes on my network that reference two Windows 2003 Domain controllers. I had them set up and working very well, until a couple of days ago when my windows admin decided to install Service Pack 1 to the 2003 servers. Now when I try to get a user list with "wbinfo -u", I get the "Error Looking up domain users" message. I can still authenticate with wbinfo -a. I can get a list of the BUILTIN groups with 'wbinfo -g'. I've tried restarting winbind and samba.. I've tried rejoining the domain and setting the auth-user with 'wbinfo --set-auth-user=username%password'. Has anyone else experienced this problem after installation of Service Pack 1 under 2003? Here's my smb.conf file:[global] workgroup = DOMAINNAME server string = %h server (Samba, Debian) security = share password server = 192.168.0.5 passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew \sUNIX\spas sword:* %n\n . syslog = 0 log file = /var/log/samba/log.%m max log size = 1000 dns proxy = No panic action = /usr/share/samba/panic-action %d idmap uid = 10000-20000 idmap gid = 10000-20000 winbind uid = 10000-20000 winbind gid = 10000-20000 winbind use default domain = yes winbind enum users = yes winbind enum groups = yes wins server = 192.168.0.5
