Please can you explain why this is so?
Auditlog is a poorly written overlay that hopefully will be deleted
in the future. It kills perf, and in general is not recommended
for use. If you want a record of changes, I suggest you look at the

Why are you stuck on auditlog? As I said, don't use it.
Sorry, I was too tired; I mean: "1. Can we use an LDIF backend with
the accesslog overlay?"
2. Has anyone written a program to convert the auditlog data to an
LDIF format that can be applied with ldapmodify?
No idea. As I said, it's not really a usable piece of software.
Similarly, I meant:

One of the advantages of syncrepl (Although I use and prefer

You can still enable the accesslog overlay regardless of what
replication mechanism is used between the mirrors.
Yes, I understand that.
As for the reliability, as I said, in my experience, delta-syncrepl
has been reliable.
But has plain syncrepl been unreliable? If so, in what way?
4. Is there any prospect of delta-syncrepl being supported with
Yes, that's a future request.
Would you suggest we avoid using mirror mode so that we can use
delta-syncrepl in order to achieve more reliable replication?
