[Samba] can't create workstation account

[Julian Pilfold-Bagwell]

Hi all,

Found this thread while searching for the problem you have and have 
found a cure that works for me.

Whenever joining the domain from a Windows XP machine it was only 
creating the Posix side of the account and not the sambaSamAccount 
that's required for a successful account creation. Found the following 
in another thread from 2005. Basically, change your add machine script 
in smb.conf from:

smbldap-useradd -w "%u"

to

smbldap-useradd -w -d /dev/null -c 'Machine Account' -s /bin/false "%m"

-d sets the home directory of the machine user to "non-existant" (/dev/null)
-c sets the gecos and may not be strictly necessary (haven't tried without)
-s disables sets a non-existent login shell

and most importantly, %m sets the account name to the correct machine 
name parameter, not user name.

Ironically, if I now run:

 smbldap-usershow jpb-laptop$

after successfully connecting my laptop to the domain, I get no entry 
returned. Slapcat'ing  my ldap database however, shows the machine 
account with all the correct Samba and Posix entries and logins work 
fine. Let me know if this works for you and post it as [Solved] if it does.

Cheers,

Jools
