Help in LDAP5.1 Consumer-supplier setup.

Hi,

I am trying to do the consumer-supplier setup for iPlanet Directory server 5.1.
I followed all the steps given in the "Configuring Single-Master Replication" of iPlanet Directory Server 5.1 Administrator's Guide.
The setup is done. I can see the supplier data getting replicated in the Cosumer server.
Now if i try to add/modify any user entry from the consumer side, it give me exception "netscape.ldap.LDAPExcpetion error: result 53 ...." However, the reverse is working fine.
It works fine on iPlanet Directory server 4.13 without any extra settings.(Thoug the configuration steps are signficantly different for 4.13)

Do I need to do any setting to make this work for LDAP 5.1? any pointers will be welcome.
