Re: (ITS#8724) slapo-pcache truncates remote results
I just cloned the source, and found where it removes the paging control.
/* NOTE: this is a quick workaround to let pcache minimally interact
* with pagedResults. A more articulated solutions would be to
* perform the remote query without control and cache all results,
* performing the pagedResults search only within the client
* and the proxy. This requires pcache to understand pagedResults. */

Well, then since you are confirming the bug, I would say this ticket
should *not* be closed.
I might just have to patch this to make it work. The client software
I'm actually working with is nextcloud, and it is *very* *very* *very*
ldap chatty. And with 2900+ objectclass=group, and 3300
objectclass=person, it runs super dog slow. Their suggestion is to
install a local ldap instance configured as a caching proxy, which has
led us to here.
I've already fixed several issues in nextcloud locally(the first one I
ran into was $limit=400 hard-coded in the group search function).
This kind of paged result handling needs to be dealt the same way an
http proxy would deal with partial content caches.
