smbpasswd replication

[richard]

Can't see how Steve? Unless you mean sharing usernames across multiple
pcs in different offices. To clarify:
our network consists of 4 offices linked by vpns through the internet.
At present we auth to an Nt4 pdc in main office which works fine until
"telstra" our isp goes down...hence my need for a "bdc" type of backup
authentication.
For us the chance of the same user/password being modified on two
different servers at the same time is negligible. and if we only
replicate the individual user/passwords that change the whole database
should remain in a consistent state....unless I've missed something?
