[Samba] Workstation joins domain but user cannot log in SMB-LDAP
Hi List,
I've done a little bit of SaMBa in the past, but new to LDAP, so bear
with me please. (It is a lengthy post...)
I've (loosely) followed this guide here:
http://www.rrcomputerconsulting.com/view.php?article_id=3
My server is a Ubuntu 8.04 LTS (up-to-date) running :
OpenLDAP: slapd 2.4.9 (Aug 1 2008 01:08:50)
buildd@terranova:/build/buildd/openldap2.3-2.4.9/debian/build/servers/slapd
Samba Version 3.0.28a
Kernel : 2.6.24-21-server #1 SMP Wed Oct 22 00:18:13 UTC 2008 i686 GNU/Linux
I got to the point where things should fall together but they don't...
What is working:
On the server:
Anonymous checking what is available works:
smbclient -L localhost
Password: <EMPTY>
Anonymous login successful
Domain=[SRECENGINEERING] OS=[Unix] Server=[Samba 3.0.28a]
... <snip>
I was also able to succesfully join a laptop to the domain.
The system even shows up in LDAP
ldapsearch -x -b dc=srecengineering,dc=int | grep lpt
# lpt-00005$, Computers, SRECENGINEERING.INT
dn: uid=lpt-00005$,ou=Computers,dc=SRECENGINEERING,dc=INT
cn: lpt-00005$
uid: lpt-00005$
Then trouble started,
I created a user using /usr/sbin/smbldap-useradd
A ldapsearch returns the user.
BUT I cannot log in using that user on a Win XP SP3.
"The system could not log you on..."
Googling things points to troubles between ldap / samba and groupmap
net groupmap list

In /var/log/samba/log.LPT-00005 I see:
[2008/11/04 14:19:04, 0] auth/auth_util.c:create_builtin_users(758)
create_builtin_users: Failed to create Users
But is NOT all bad because using 'root' to log in on the WinXP laptop
'works'.
(There are still some err messages in the samba logs, but I see a Z:
drive on the laptop pointing to the SaMBa server)
What else?
I also see a lot of these:
