I missed to include "/usr/share/openldap-servers/slapd.acl" in proxy.conf(Consumer proxy configuration).I included this, still getting same error in consumer proxy log.

syncrepl_entry: rid=001 LDAP_RES_SEARCH_ENTRY(LDAP_SYNC_ADD)

syncrepl_entry: rid=001 be_search (49)

syncrepl_entry: rid=001 dc=suretecsystems,dc=com

null_callback : error code 0x31

syncrepl_entry: rid=001 be_add dc=suretecsystems,dc=com (49)

syncrepl_entry: rid=001 be_add dc=suretecsystems,dc=com failed (49)

do_syncrepl: rid=001 rc 49 retrying (4 retries left)

I have one question consumer proxy configuration .
