[Samba] Strange Win7 message

[Martin Hochreiter]

  Hi!

I don't know if this is Samba related, but I just try - maybe someone 
could lead me in the right direction:

I am using Samba 3.5.4 and I just changed all my workstations in my 
domain to Windows 7.
On one worksstation it is not possible to log on with one certain user 
(all the others a working).
b.t.w. We use openldap as database for samba.

If you logon with that user, the roaming profile is loaded and suddenly 
win7 stops with
"The local session manager fails to start" and a message that a cache or 
something is to
small for the value. The user login is cancelled ... it does not matter 
if i make it to a local stored profile.

Can somebody give me a hint?

regards
martin
