I have at last upgraded a system from using slurpd (debian etch, slapd 2.3.30) to using replsync, at least that was the intention.

I believe you mean SyncRepl (Sync Replication).

What version of OpenLDAP is on the master? 2.3.30?

===================

And on slave:

# updateref ldap://masterserver.uninett.no/

I'd still set updateref, so clients know where they should send updates.

syncrepl rid=123 provider=ldaps://masterserver.uninett.no:636/ type=refreshOnly interval=00:00:00:10 retry="60 +" searchbase="dc=foo,dc=no" scope=sub schemachecking=off bindmethod=simple binddn="cn=admin,dc=foo,dc=no" credentials="f00bAr123"

I highly advise using refreshAndPersist rather than refreshOnly.

When I start slapd on the slave I get on the slave:

18:37:50 server.foo.no slapd[7971]: @(#) $OpenLDAP: slapd 2.4.23 (Jul 5 2010 18:35:50) $ ^Iroot@localhost:/home/kolla/openldap/openldap-2.4.23/debian/build/server s/slapd 18:37:50 server.foo.no slapd[7972]: slapd starting 18:37:50 server.foo.no slapd[7972]: syncrepl_message_to_entry: rid=123 mods check (objectClass: value #0 provided more than once) 18:37:50 server.foo.no slapd[7972]: do_syncrepl: rid=123 rc 20 retrying 18:38:50 server.foo.no slapd[7972]: syncrepl_message_to_entry: rid=123 mods check (objectClass: value #0 provided more than once) 18:38:50 server.foo.no slapd[7972]: do_syncrepl: rid=123 rc 20 retrying ===================

I would advise you start the slave with the "-d -1" options passed to the slapd binary, so you can see exactly what the master is sending to the replica. It sounds like it is sending invalid data. This could be a bug in the version that the master is running. You might want to try running a separate master for testing, that uses OpenLDAP 2.4.23 as well. There have been a multitude of fixes to the syncrepl code in OpenLDAP since the 2.3 series.
