Since we're on the subject of Samba over the WAN....

(BTW, I'm running three offices with a Samba 3.0.9 PDC and two Samba 3.0.9 BDCs 
over an FreeSwan based WAN and it works just fine.  The WINS server is a must 
in my book though.)

Last Thursday and Friday, one of the remove office's WAN lines went down.  
While the outages were significant, nothing major happened because of it.  But, 
it got me thinking about what *could* have happened and that has raised these 
questions.

Background: All servers running RHEL 3.0, up2date'd.  Samba version is 
3.0.9.something.that.RedHat.Adds  OpenLDAP used for ldapsam password backend.  
Master OpenLDAP server is located in my office, each office has a replica.

1).  If someone would have decided to change their password while the line was 
down, what would have been the net effect?  I know the change would not have 
been applied to the replica LDAP server, but would it have been queued until 
the Master LDAP server could have been contacted?

2).  I know that each workstation in the domain changes its machine password at 
a random time, what would have happened during this process if the WAN was down?

3). Are there any other problems that could be caused by a WAN outage that can 
be called disasterous?  What would those be?

4). Any recommendations to minimize No. 3 above?
