Re: (ITS#6668) MemberOf Overlay
thank you for your comments.
I'll happily make more details available since I have the feeling that
there is some value in doing so and
quite a few people might benefit from a clarification of:
which have been commented in
with "I think that the example in the docs is clear enough if you think
it over :)"
the example seems indeed to be clear. The configuration and
installation of the memberOf functionality is IMHO not.
My first bug assumption here is that a non installed memberOf overlay
should lead to
some kind of visible reaction in the logs or in an ldapsearch query at
least when using some verbose or debug
option. At least I did not find any mention of a way to make this
happen. So a system with a memberOf Overlay installed
might show results with a correct query where one that has none
installed will simply show no results.
So someone trying to tryout memberOf will not know whether the query is
incorrect or the overlay is simply not installed.
Even knowing that memberOf is an overlay is something people need to
find out. My feeling is that memberOf is a default installation
part in other ldap implementations. I think I have seen a request to
make it part of the default installation for openldap. I would support this
request given that this would make sure that distributions are forced to
contain it and that overlays are not considered to be optional.
If you look for the overlays in rpmseek you'll see that it seems to be
not-so-common to put them in to distros as it might look from your
