[Samba] Samba 3.0.22-11 as PDC with openLDAP 2.3.19 => Problem with Shares

Hi there!

To set up a samba PDC with openLDAP on my openSUSE 10.1 x86_64 I followed
this howto: http://en.opensuse.org/Howto_setup_SUSE_10.1_as_Samba_PDC

Every service seems to be running now but now I'm stuck. I was able to join
a clean Windows XP Pro test machine to my Domain and I'm able to log on as
normal LDAP user. The home-share is mounted and even a login script
(actually just the DOS command "PAUSE") works fine.

Now I try to create shares on the PDC but it doesn't seem to work to allow
LDAP groups access to shares.

[web]
comment = Intranet
path = /data/srv/www
create mask = 0600
directory mask = 0700
browseable = Yes
guest ok = No
force user = root
valid users = "Web Admins"
admin users = "Domain Admins"
read only = No

The user trying to access this share is a member of both groups "Web Admins"
and "Domain Admins". When accessing the share Windows keeps prompting for
account credentials in an infinite loop. The log (samba logs with level 256)
does not state anything.

Changing the share to:

[web]
comment = Intranet
path = /data/srv/www
create mask = 0600
directory mask = 0700
browseable = Yes
guest ok = No
force user = root
valid users = @"Web Admins"
admin users = @"Domain Admins"
read only = No

This makes Windows hang for quite a long time when trying to access the
share. Finally I get a dialog box indicating that I was denied access and
the share wouldn't any longer being available.

Log states:

(I changed the username and domain name entries in this log) 

Changing the share to:

[web]
comment = Intranet
path = /data/srv/www
create mask = 0600
directory mask = 0700
browseable = Yes
guest ok = No
force user = root
valid users = +"Web Admins"
admin users = +"Domain Admins"
read only = No

This is leading to the same behaviour in Windows.

I don't see the error. Any ideas?

I was looking for a kind of tutorial for using samba along with LDAP but
didn't find a thing covering the issues I'm looking for. I'm searching
advice for managing accounts, groups, printers, rights, logon times and
allowed workstations, standard profiles, logon scripts, policies for Windows
workstations and so on. Would be great if anybody could help me with a link
here ;)

Thank you in advance for your kind help!

Manuel
