samba 3.5.6 as PDC & LDAP - roaming profile problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi all;

for few weeks I'm trying to implement a new samba PDC server for my school.
It is based on debian squeeze and samba 3.5.6 with lDAP backend.
I was able to join a computer into domain, LDAP is working, mapping home
drive for users also.
It seems that almost all works good but with one exeption. The one thing
which is broken is roaming profile support.
When user is logging into domain windows (I tested win XP prof SP2 and win7
prof SP1) always said:
"Windows cannot locate the server copy of your roaming profile and is
attempting to log you on with your local profile. Changes to the profile
will not be copied to the server when you logoff. Possible causes of this
error include network problems or insufficient security rights. If this
problem persists, contact your network administrator.
DETAIL – The network name cannot be found."
and
"Windows cannot find the local profile and is logging you on with a
temporary profile. Changes you make to this profile will be lost when you
log off."
It looks strange because when I put into netlogon share default profile
windows take it ( I see that background color in windows is the same like I
prevoiusly set into default profil), user is able to browse his profile
directory and create inside this dirs and files.In samba logs there are no
errors, I can see that /profile share is assigned into user.
On windows side in c:\windows\debug\userenv log there is:

I googled few days I tryed all what I can find but with no luck. It will be
great if somebody could help me with this because I have no idea what is a
root cause of my issue.
