Hi All, I've been scratching my head at this problem for a while now. I recently upgraded from Samba 3.0.25 to Samba 3.4.2. We use Samba as our domain controller. However, ever since the upgrade, new machines have been unable to join the domain. In Vista, I can the error that I am using a bad username or password. In Win 7 Pro, I get an error about the action not being supported. It seems unlikely that it is truly a password issue as our Domain Admin accounts can log into machines that have previously joined the domain with the proper password. Does anyone have any ideas on what it could be? Our smb.conf is as follows: [global] unix charset = CP850 workgroup = QUIACORP server string = Samba Server Version %v netbios name = europa hosts allow = 127. 192.168.1. log file = /var/log/samba/log.%m max log size = 50 security = user passdb backend = tdbsam:/var/samba/private/passdb.tdb encrypt passwords = yes unix password sync = yes passwd chat = *New*password* %n\n *Reenter*new*password* %n\n *passwd:*\ all*authentication*tokens*updated*successfully* pam password change = yes domain master = yes domain logons = yes logon script logon path add machine script = /usr/sbin/useradd -s /bin/false -d /dev/null '%u' delete user script = /usr/sbin/userdel '%u' rename user script = /usr/sbin/usermod -l '%unew' '%uold' add user script = /usr/sbin/useradd -M '%u' add group script = /usr/sbin/groupadd '%g' add user to group script = /usr/sbin/usermod -G '%g' '%u' set primary group script = /usr/sbin/usermod -g '%g' '%u' enable privileges = yes local master = yes os level = 99 preferred master = yes wins support = yes name resolve order = wins lmhosts hosts bcast load printers = yes cups options = raw [shared] path = /storage/sdb2/SHARED comment = Shared file area browseable = yes writable = yes create mode = 0664 directory mode = 0775 inherit permissions = yes [rhome] path = /rhome comment = Home directories browseable = yes writeable = yes create mode = 0644 directory mode = 0775 Any help would be much appreciated.
