[Samba] Problems with 2.2.8a PDC/3.0.2aBDC and XP

[Eugenio Ruivo]

Hi,

I continue to have strange problems with out attempt to migrate from 2.2.8a to 
3.0.2a.

After a couple of days around the subject my last attempt at trying to figure 
out what is happening was as follows:

MDK 9.1 with Samba 2.2.8a as PDC with LDAP, this is our current production 
server (we want to upgrade to MDK 10.0 and Samba 3).

The idea is to migrate to a temporary server to free ou main server for the 
upgrade. This server has MDK 10.0, Samba 3.0.2a, OpenLdap, etc.

Our first attempt was to install the LDAP tree on the temporary server with 
the new schema for samba 3 by exporting to ldif converting to sambaSamAccount 
and applying the edited ldif (some where along the line we also tried pdbedit 
-i ldapsam_compat:/oldserver) and configure the backend as 
ldap:ldapsam://localhost

At a certain point we got everything to look ok when working from the two 
linux servers.

Whwn we try browsing from one of our XP Pro computers (that authenticates and 
logs on against the PDC main server) for the temporary server (BDC) we can 
find the server but can't see the shares. It complains that the network name 
is no longer valid.

After trying every thing I could think of I decided to go to another approach, 
We had another server that also has the same software so we configured as BDC 
but using ldap directly of the main server as passdb backend 
ldap:ldapsam_compat://x.x.x.x (IP of our PDC which hosts the LDAP install 
also).
We also edited /etc/ldap.conf accordingly (checked getent passwd and group. 
All visible an ok).
We joined this server to the domain ok.

Well when browsing the domain the server doen't show, but browsing directly 
for \\server_name pops up the authentication login window but it doesn't 
validate.

Anybody have any suggestions?

Thanks,
Eugenio Ruivo
