the bdc should point to its local ldap (slave) server.  this is what 
gives you the ability to run as a *backup*.  if you had both pdc and bdc 
pointing to the master ldap server and that server went down, your bdc 
is worthless.

read the "official how-to" at samba.org.  it describes the various 
options for setting up a pdc and bdc with ldap.


by far, the best is pointing the pdc at the master ldap server 
(read/write) and pointing the bdc at the slave server (read only).

you will also need to point your nsswitch.conf and your ldap.conf on the 
  bdc to the slave server (assuming your samba bdc is on the same host 
as your slave ldap server.
