samba - May 2003 - Samba+PDC+LDAP...some success...need troubleshooting though

Morning everyone.

Well, I was finally able to add a workstation to my Samba PDC running LDAP 
this morning.
However, it is not actually doing it the way I would like to.

The problem I was running into is that the script I specified in my 
smb.conf file to automatically add machine accounts is not working 
correctly. In order to add my test machine to the PDC today, I had to 
manually enter it. Although this is not too bad, I would prefer it be done 
automatically through the script.

So what I am attempting to do know is find out why computers are not being 
added automatically via the script.
I thought i'd post a few things here and see if anyone has any ideas.

Here goes:

My script in smb.conf:

add user script = /usr/local/sbin/smbldap-useradd.pl -w -d /dev/null -c 
"Machine Account" -s /bin/false %u

domain admin group = @Administrators

I created a user called ldapadmin and added the account to the 
Administrators group. I made sure the smbldap-useradd.pl script had root 
Administrators rights to it.

I'm a little unclear as to why the script is not working correctly. Anyone 
have any thoughts?

Thanks everyone.

Jason
