Interesting.

So you basically have some sort of script that checks responsiveness. If none, it reconfigures slapd.conf and restarts the process? Seems like quite a bandaid, but it'd work.

We are running OpenLDAP 2.4.23. Part of our implementation proxies to an

Active Directory server. Whenever connectivity to the AD server is
interrupted, queries to the non-proxied portion of our implementation take a
very long time and cause many issues with querying services.
Based on the config info you provided, I don't see how that's possible. You have 3 database sections of note, and they are all independent. Queries to any of the first two databases cannot be affected by anything in the back-ldap database, unless you've deleted something crucial from the censored config you sent.
The doc sections you quote are not relevant, I suggest you re-read the slapd-ldap(5) manpage more carefully. 


I reported a similar issue a couple of years ago:
Your issue was reported against back-meta, this post is about back-ldap. The configurations are not similar at all. 

http://www.openldap.org/its/index.cgi/Incoming?id=7372;selectid=7372

That was with 2.4.32. I don't think it's been fixed since, but I've worked

around it with a slightly unpleasant out-of-band check on our domain
controllers which reconfigures OpenLDAP when it detects a DC going out of service.
From what I see in the mailing list archives, there was nothing to fix. The timeouts all worked as designed when tested locally.
