[Samba] Multi-homed Samba PDC problem

[M. D. Parker]

The samba PDC is the only PDC for the given domain.

Maybe a picture:

	system A <----private network----> system B <-----> ... system N
		|	(possibly other system)	|				|
		|					|				|
		|					|				|
		|					|				|
		|		public network	|				|
		V					V				V

			WINS server on public network

Both system A and system B are in the same domain.  Only A is the Samba PDC.

so question is when I do not mention the private interface in the interfaces
statement things work OK.

However, when I activate the private interface on the PDC, it times out
requests
to the WINS server, does not apparently become the domain master browser
because
of this.  However access seems to work just fine otherwise from what I can
see.

Why does adding the private network to the samba configuration cause this
type of problem?

Mike

Hi Mike,

hope i understand everything right,

> Question: What type of problem is this?  and how serious?
It is a windows network problem and or a collision between two PDC´s.


> Question: Ok, how do I correct it?
There are some possible solutions for your problem:

a:

If there is allready a PDC (W2K/NT) then change on
the samba PDC the domain, and create on both sides an
interdomaintrust relationship

b:
Change the Samba config, that it is a Domainmember-Server.
