Yes.  But I don't see it as a real problem : before copying the data
from the ldap server to the qmail database, I do a semantic check of the
contents of the directory (valid email adresses, no duplicates, etc.)
so it's easy to check for and report illegal manager entries.

This would work for me, and I believe it's a reasonable design.

Now that I think about it, I have something else to propose, which may
or may not have been discussed before on this list but I'm fairly new to
all this :

When I read the docs for the Netscape Directory server, I found an "add"
and a "delete" right in the access list.

I was quite surprised when I came to OpenLDAP to find no similar
concept, and I had to dig into the source to find out how "add" was

How difficult would it be to add such an access right ? Wouldn't it be a
cleaner way of dealing with all this ? Of course I may not be aware of
all the issues, maybe it's not flexible enough.

Also, is the strict ordering write > read > search > ... necessary ?
Couldn't we refine the rights in a non-strict ordering fashion, say :
    write (= modify only)
maybe others I forget.

Or is all this mandated by the LDAP specs ?

While I'm on the topic, for those who know the code, how difficult would
it be to add netscape-like ACLs directly into the entries (the aci:
attribute) ?
was very interesting to read.
