Yes, though that's not the fundamental issue, since I can work round cn=config
I've done some more investigation and I can now see what is causing the second problem.
When I change the olcSyncrepl values for the main database to use cn=accesslog
(i.e. to use delta-syncrepl rather than syncrepl), the slapd logs are flooded with messages
"do_syncrep2: rid=xxx (4096) Content Sync Refresh Required"
I have worked out why this is: the slapd server corresponding to rid=xxx is trying
to search for entries in its cn=accesslog database with entryCSN <= the contextCSN of its
main database, but failing to find any matches, because the cn=accesslog database was
created after the last change to the main database that happened through this server.
I think I can work round this by making sure an LDAP modify is done to the main database
against this server after the accesslog database is created, but this does seem like a bug to
