samba - Jan 2004 - LDAP - _samr_open_domain: ACCESS DENIED

Hi,

I am trying to get samba running with LDAP password backend, but having 
some trouble with the rights.

Dist. : SuSE 9.0
LDAP: OpenLDAP 2.1.22
Samba: 3.0.1

It work's great when i login in for a Win98 box, but when i try to 
import a WinXP box i get the following in my log file.

//--snip--
[2004/01/27 20:36:25, 2] auth/auth.c:check_ntlm_password(305)

I suppose my problem is in the groupmapping's. ?
My current mappings are like below:

Domain Admins (S-1-5-21-3079347702-147214601-1898991890-512) -> Domain 
Admins
Domain Users (S-1-5-21-3079347702-147214601-1898991890-513) -> Domain Users

Guests

Domain Computers

This is the default after running "smbldap-populate.pl" from the
ldap-tools.
 From the documentation, the "Domain Admins" have to be mapped to 
unixgroup=root or another group with gidnumber=0 (Right ?)
Now, executing "net groupmap modify ntgroup="Domain Admins" 
unixgroup=root type=domain" is succesfull, but the mappings don't
change
"Domain Admins" is stille pointing at "Domain Admins" ?

I also tried to create a posix group in LDAP with gidnumber=0, and made 
a mapping from the "Domain Admins" but the mapping still don't
change.


Could some one kindly point me in the right direction.

Thanks.


Best regards
Erik
