See below.  Se this to yes.

If the remote LAN cannot 'see' (in the netbios sense) your main PDC,
make the remote 'DC' a PDC.  It will then act on the local read-only
LDAP slave, and update the LDAP master when it needs to.

make sure your LDAP slave is setup for update referrals.

Also see the 'ldap replication sleep' parameter.
