[Samba] Multipile domain controllers?

[samba at biased.org]

Hello,

Have set up a network with multipile Samba PDC's - one each network segment in
different locations - i.e. 10.3.x.x in Cardiff, 10.2.x.x in Glasgow with their
own PDC server.  Anyway, the networks are connected to each other via VPN - is
it possible for a computer in Cardiff to log on into the PDC controller in
Glasgow, even tho it's already set up to log in the Cardiff PDC?

Thanks very much for your help in advance!

Cheers - Piers
