Roaming profile problem with LDAP backend Samba PDC

I've setup a LDAP backend Samba PDC. I can gain access to shares and login with a user that is in LDAP, but have a prblem setting up the roaming profile stuff. I've been trying to solve this problem for some time now, and have tried everything I could think of, but without much luck. :x I keep getting the following error messages:

"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. Plausible causes of this error include network problem or insufficient security rights. If this problem persists, contact your network administrators. DETAILS - The network path was not found."

Followed by: "Windows cannot find the local profile and is logging on with a tempory profiles. Changes to this profile will be lost when you logoff."

Here is my smb.conf:

ldapsearch gives me

Code:

I can acces \\Server\profiles, \\Server\netlogon using my tester account. /etc/passwd contains no line with the user tester. And I can login under SSH with the tester account.

ll /disk/{netlogon,profiles} gives me:

Code:

I've populated the LDAP with smbldap-populate -u 10000 -g 10000 -r 0000. I did notice various entries with out of range uid and gid number. nobody (uid 999 gid 514), domain admins (gid 512), domain users (gid 513), domain computers (gid 515), Administrator (gid 544), Account Operators (gid 548), Print Operators (gid 550), Backup Operators (gid 551), Replicators (gid 552)

/var/messages shows:
Aug 3 09:16:55 Server slapd[983]: nss_ldap: could not search LDAP server - Server is unavailable

But it works. Searching on the internet told me this last message was bogus.
 
I've enabled debugging in Windows Domain using:
http://support.microsoft.com/default.aspx?scid=kb;en-us;221833

I find it strange that it first tries \\%L\profiles\testers. This is the log.

Code:
