OK, thanks. I had a look through the available data and I think these
would be best:

nsDS5ReplicaHost||nsds5replicaLastUpdateStatus||nsds5replicaLastUpdateStart||nsds5replicaLastUpdateEnd||nsds5replicaLastInitStart||nsds5replicaLastInitEnd||nsds5replicaUpdateInProgress

OK, will do, once I've figured out a few more things. I want to enable
this for the PKI-CA directory too. I changed the dn to "dn:
cn="o=ipaca",cn=mapping tree,cn=config" and added this to my server on
port 7389. Using targetattr=*, everything works fine, but when I
restrict it to the list of attributes above, I don't get any results.
Is there another attribute I need to add?

Thanks,

Dan
