Just a heads-up, I'm going to merge the LDAP caching patch later today, PR https://github.com/freeipa/freeipa/pull/5681

Caching is enabled by default and some metrics will be visible in the Apache log when the server is in debug mode, like:

ipa: DEBUG: FINAL: Hits 1 Misses 3 Size 2

There is a very simple log parser to determine cache usage in contrib/cachelog if you want to check on how much/if the layer helps.

Let me know if you see anything really odd happen.

To disable the cache add ldap_cache=False to /etc/ipa/server.conf and restart httpd.
