Hi, I'm setting up a PDC, but joining the clients (w2k, nt4) fails. I use this in smb.conf: add user script = add user script = /usr/sbin/useradd -d /dev/null -g 100 -s /bin/false -M %u Just using the script I get the error: "no account in domain" under linux. Useradd itself works but it seems to fail for samba. All clients originally used a nt4 PDC. Now this nt4 PDC must be changed to a samba PDC (samba 2.2.7a and 2.2.8 a bit later). I tried to create a machine account manually to figure out how it works. After adding the entries manually with: test:~ # passwd -u r13-4$ passwd: Unknown user r13-4$ test:~ # /usr/sbin/useradd -g 100 -d /dev/null -c "Tutoren-r13-4" -s /bin/false r13-4$ web:~ # passwd -l r13-4$ Password changed. test:~ # smbpasswd -a -m r13-4 Added user r13-4$. Windows still says something like: account not existing or wrong password (original message in german). I looked already in Samba-PDC-HOWTO.html. Probably it's the same error like: "/The machine trust account for this computer either does not exist or is not accessible./" What does "Ensure the domain admin user system is working." exactly mean? I must get this running, thanks for any help or hint.
