Excellent, thanks.

I've run an 'init' of ohm and all of the memberOf attributes were
removed. I then ran fixup and they were re-added correctly, so that
script seems to be working fine. I'm not sure why the memberOf
attributes aren't being replicated during the initialisation though.

I see this error in the logs:

- skipping cos definition cn=account
inactivation,cn=accounts,dc=example,dc=com--no templates found

Could this be causing the replication to stop? I can't find this
template (/etc/dirsrv/schema/*) on either curie or ohm, so I'm not
sure where it's coming from. I can find 'nsAccountLock' though....

I haven't seen the admins memberOf log message since I removed admins
as a nested group (as expected).

Thanks,

Dan
