samba - Dec 2002 - S3.0a21 -> Creation of lokal Profile-Folder failed...

Hi there,

currently i'm running a RedHat 8.0 on I386 with
Samba 2.2.5 using LDAP as User- and Group-Database.
Samba is configured as a PDC.

In this environment everything (ok... the most :) is
working fine.

Now I've tested to switch to samba 3.0a21. No compile-problems.
No installation-problems. Access to shares works fine (after
little start-problems with samba-ldap-config). Joining the
Domain works much better than in 2.2.5

The Problem: After Joining the domain, domain-users and
domain-admins that are logging into the W2K-Workstation (SP2/ german)
are not able to create a local profile folder.
(On german W2K in "C:\Dokumente und Einstellungen")

There is only a folder TEMP that is removed automatically after
logging off. Error messages at logon notifys me that there are
problems writing the profile to the local disk. There are no
hints to an denied Access on the profile folder.

In another test I used smbgroupedit to assign Linux-Groups to
Samba-Groups but the result doesn't change.

The Domain-Administrator is member of group "Domain Admins"
that is member of "Administrators" on the W2K-Workstation.

Any hints what to do?
Any hints where to get a how-to creat a correct LDAP-Tree for
Samba 3.0?

ThX...
Chris
