[Samba] Loooooong logon-times using samba 3.5.6 and Windows 7

[Hans Otto Lunde]

Dear samba-users

We are experiencing some rather long logon times using SAMBA 3.5.6 on Debian Squeeze + Windows 7 and while trying to find out why we raised the loglevel to 5 resulting in a rather large logfile. But this did give us a hint as to why we experience so long logon times. It seems that samba is going through the whole user-database with all usernames and machine-accounts.
Eventually the user is logged in, but the experience is not ok, because of the long waiting-time.

Has anyone had a similar experience?

Here is a snippet from the log and below the smb.conf

[2011/02/11 09:41:22.058237,  5] passdb/pdb_smbpasswd.c:527(getsmbfilepwent)

  getsmbfilepwent: end of file reached.

When it reaches this line it starts all over again and continues doing so for about 30 seconds.
This series of events has us quite baffled and any help resolving this would be greatly appreciated.
