Multimaster replication problem

Hi All,
 

 

We are having problem making multimaster replication work. Any help
would be greatly appreciated.  Enabled multimaster support as per howto
document. Not able to add entries on either server if in slapd.conf
updatedn
line is added. If we add updatedn line in slapd.conf we observe the
following debug message while trying to add new entries with ldapadd

ldap_add() : No object found error. 


Also, slurpd is reporting following errors:
