[Samba] Separate PDC and file server

[Massimiliano Mirra]

First of all, sorry, this must have been discussed before but I
couldn't come up with a good set of keywords for googling.  Feel free
to slap with a msgid or an URL. :-)

I successfully set up a PDC that authenticates a small Win 2k/XP LAN.
It fetches auth info from a LDAP server and also serves home
directories.  The setup works with both 2.2.6 and 3.0a20 on Linux.

Now I'd like to move the homes to the real file server, which runs
Tru64.  Which is the best setup?

- File server exports homes to PDC via NFS, PDC re-exports them via
  Samba.  Pros: easiest, no changes in current configuration, and
  users have to authenticate just once to the PDC.  Con: two exports
  instead of one.

- Accounts are changed so that SMB homes aren't imported from
  \\PDC\username but from \\FILESERVER\username.  Pro: just one
  export.  Cons: users have to authenticate again to the file
  server, and the the file server's nsswitch must be configured to
  lookup user info via LDAP.

- PDC gets request for the user home share and forwards it to the file
  server transparently.  Is this possible?  (Con: the file server's
  nsswitch still has to be configured for LDAP.)

Thanks for any input.
