[Samba] machine profiles?

[Eric Lopez]

I have configure Samba to not store profiles (logon path= ), Windows 
creates a local profile on the computer when the user logs in as intended.
A machine account gets created every time a computer joins a domain, 
apparently samba is looking for a profile for the computer on the server 
every time someone connects to it.

[2008/05/05 09:21:32, 0] smbd/service.c:make_connection(1111)
  machine34 (4.5.6.7) couldn't find service profiles
[2008/05/05 09:21:32, 0] smbd/service.c:make_connection(1111)
machine34 (4.5.6.7) couldn't find service profiles

Samba is configured with an LDAP backend, computers are created with the 
sambaAccount objectClass and their home directory is set to /dev/null... 
Any ideas?
Thanks,
Eric.
