[Samba] Migrating from Samba 2.2.8 to 3.x on different machine

[Spike Burkhardt]

Jorick,

  If you're having problems then I'd scale back on all the changes.  Basically
I'd install the 3.0.10 software, copy over the smb.conf and first see if that
works.  I'd then do the domain name, switch to ldap & finally to the rename.
This last part depends on whether ldap has the desired username.  See below
for how I'd attack the problem.

Do this first.

   * Install 3.0.10 on the new machine.
   * Copy the smb.conf file from the old machine to the new machine.
   * Startup and test.
   * If it fails, post the results with the appropriate log entries and your
     smb.conf file.

     - switch to a ldap backend

Do this third.

   * After the first two steps are successfully completed, populate LDAP with
     the appropriate info without the renaming of accounts.
   * Make your smb.conf changes.  This could be where changing company names
     would make a difference.  You'll need to know this information such as
     OU, admin password...
   * Verify that samba is connecting to the LDAP server.  Even at the lowest
     levels of log messages, you should see a "connected" message.
   * After successfully connecting and mounting a share with LDAP add the new
     usernames without taking out the old ones.

Do this second.
Are you saying that the workgroup has changed?  If so then change it in
smb.conf.  If the workgroup hasn't changed then there is no need.

Do this last.

   * Instead of renaming the LDAP usernames, add the new usernames.
   * Mount a share with the new username
   * If not successful then post the results with the appropriate log entries
     and your smb.conf file

HTH.
