[Samba] Suggestions for moving a PDC function

[Simon Matthews]

I currently have a server which is both the PDC for my domain and the file
server for the network.

I need to split these functions and move the PDC function to another box,
while leaving the original server as the file server on which home
directories and roaming profiles are stored. User credentials are stored in
a tdbsam database and I am running Samba 3.5.

Does anyone have any pointers on what to move and any potential pitfalls in
the process? I have always used the same machine for both the PDC and file
server, so this is somewhat unknown territory for me. I assume that the
file server will still run samba, and I will change the "domain master = "
and "domain logins = " to no in both cases. Also "security =" should be set
to "security = domain" and add set up a machine account on the file server
which is then joined to the domain?

What files need to be moved to the new samba server? I see that there are
files in /var/cache/samba (it's a Gentoo system) which I assume also have
to be put into the proper place on the new server. Is there anything else I
need to look for.

Many thanks for any suggestions.
