Dualing Sambas (Or dueling Sambas, depending on how you want to l ook at it)

SURS is a confused set of concepts, confused because it's been talked
to death.  The idea is to provide a translation table between UID
numbers (Unix) and RID numbers (NT) -- but the specific mechanism is
sort of up for grabs.  I don't know how the things you mention are
implemented.

Good idea.  As long as you can keep the two straight in your head.

Not only 'interfaces=', because that is only a hint in case Samba can't
detect the right interfaces on its own (some Unices make this
difficult).  Also use 'bind interfaces only = true' to enforce your
choices, as it were.

...And that's about it.  The one big problem some people have with
dueling Sambas (I like that phrase) is that they fight for control of
the .pid and lock files.  To avoid that, just make sure the
compile-time defaults are set to different directories.

Make it a member server.  The two will share the /etc/passwd file, and
thus the usernames.  HEAD does not need a smbpasswd file, naturally,
since it is in 'security = domain' mode.

> Do I need them on different ports, or just different ip's?

Just different IPs.

I've never done it before but I intend to test it soon.  We are getting
a new server in for which this would be helpful.
