-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I tried to setup replication on two ldap servers : a master and a slave. The master is configured like this (slapd.conf) : database hdb suffix "dc=test,dc=fr" rootdn "cn=root,dc=test,dc=fr" [...] overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100 The slave is configured like this (slapd.conf). I tried to make a very simple setup : syncrepl rid=001 provider=ldap://my-master:389/ searchbase="dc=test,dc=fr" bindmethod=simple binddn="cn=root,dc=test,dc=fr" credentials=password type=refreshAndPersist retry="5 +" When I restart my slave I got this error in logfiles : Sep 24 11:08:37 kyo slapd[2296]: syncrepl_message_to_entry: rid=001 mods check (postalAddress: value #0 provided more than once) And replication stops. Master and slaves are installed from debian squeeze packages : root@kyo:/var/lib/ldap# slapd -V @(#) $OpenLDAP: slapd 2.4.23 (Sep 13 2010 07:04:08) $ @borges:/home/devel/openldap/trunk/debian/build/servers/slapd libbdb version is 4.8.30. Replication works well with a 2.3.20 slave, so i think i missed something on 2.4.23 slave configuration.
