Description Patrick Pätschke 2005-04-05 12:08:03 UTC
I tried to upgrade my 1000+ Users/Machines installation from 2.2.7a to 3.0.13.

- after upgrading *ALL* Windows NT4 Clients (SP4 to SP6a) failed to logon to the
domain. All WindowsXP-clients worked well.

- Removing the NT4 clients from the domain and readding them only partially
solved the problem, since the User where no longer able to read their former
registry settings from ntuser.dat.

Step by Step:

Upgrade to samba-3.0.13 with the follwong changes to the smb.conf:
first tried with: 
    passdb backend = smbpasswd:/var/samba/logon/private/smbpasswd
  then moved to: (used pdbedit to convert the smbpasswd)
    passdb backend = tdbsam:/var/samba/logon/private/smbpasswd.tdb 
  without noticeable changes.

    dos charset = CP850
    unix charset = CP850
  to retain character-set compatiblity !

Here is my smb.conf file of the logon-server:
   workgroup               = testdo
   netbios name            = logon
   domain logons           = yes

I doubt there's much that can be done to follow up on this one now.
