[Samba] Samba Member Server Authentication

[Henrik Zagerholm]

Hi list,

Scenario:

1. HQ has a Win 2003 PDC

2. Branch Office has a Samba ADS Member Server

Is it possible for a Samba ADS Member Server to handle the Windows  
Client Logons if the WAN connection between the Win 200x PDC is broken?

After reading this I got a good understanding on ADS members
http://us1.samba.org/samba/docs/man/Samba-Guide/unixclients.html#adssdm

But I also would need LDAP replication if I want the server to handle  
logons in case of WAN failures right?

Thanks for your help.
Henrik
