samba - Nov 2002 - How to configure Samba to use multiples ldap servers

Hi all,

I have two Samba+LDAP (PDC and BDC) that works fine, but I have the 
following situation: I have a LDAP Master and two LDAP slave's servers 
(OpenLDAP2). When the Master is down, the Samba cannot authenticate the 
users (its logic). My question is: how to configure the Samba to use 
more than one LDAP server ??? Samba can use the ldap srv DDNS registers ???

Someone can help me ???

With best regards,

Fabiano Felix
