[Samba] Need help configuring Samba3/LDAP PDC

Hello all,
I'm following along in chapter 6 of John Terpstra's "Samba 3 By
Example"
and I've got everything working great up until the point where I join 
the machine to the new domain (step 17 on page 155).  The command *net 
rpc join -U Administrator* fails with the errors below.

palpatine:/var/lib/samba/sbin # net -d 4 rpc join -U Administrator

I've already set Administrator's password with *smbpasswd *and 
*smbldap-password.pl *but I still cannot authenticate.  Anonymous access 
(e.g. *smbclient -L localhost -U%*) works fine so it seems that there is 
something wrong with the LDAP SAM.  I am using the same LDAP directory 
to authenticate linux clients and provide autofs maps and everything is 
working fine... except for Samba.  Has anyone else encountered this 
problem?  Tridge, Terpstra, Allison, are you out there?

I have torn down the LDAP/Samba stack several times and rebuilt it from 
scratch.  I get the same behavior every time.
I am running on SuSE 9.1 using openldap 2.2.6 and samba 3.0.4 (SuSE 
packages).    Thanks in advance!

Hello Rich (and others), thanks for responding.  I turned up the 
loglevel, fixed some configuration errors in smb.conf, and commented the 
root= entry in smbusers. You were right, Administrator was being mapped 
to 'root'.  Now I can authenticate LDAP users in Samba, e.g.
'smbclient
-L localhost -U Administrator' works properly.  Unfortunately I still 
cannot join the PDC machine to the domain and I think I know why.

When I run 'net rpc join -U Administrator' the machine account gets 
created but it is a posixAccount instead of a sambaSamAccount.  In other 
words it is a normal unix user account that is missing all of the 
samba-related fields.  Samba is calling the IDEALX smbldap-useradd.pl 
script to create the account but obviously I've got an error 
somewhere... the user accounts it creates are not samba-capable.  Does 
anyone know how to fix this?  Did I miss something in smbldap_conf.pm?

On a related note, I've imported lots of NIS data into this LDAP 
directory, so I have lots of valid Unix accounts.  These are working 
properly on LDAP-enabled linux machines, but how do I 'convert' them for
use with Samba?  Ideally I would like to have one record for each user 
that contains all of the samba data as well as the unix data.  Is there 
an easy way to add the appropriate samba fields to 'normal' 
posixAccounts?  Is there a FAQ that covers the procedure?  Any help 
would be welcome.

thanks in advance,
aaron
