Tune when sssd goes into offline mode

Question

I have a linux server with sssd using an ldap server for the auth backend. The connection to the ldap server is flakey, so I get authentications which are fine and then suddenly one will take forever and timeout, only to be fine the next time it tries.

I'm trying to tune sssd to use the cache more often and quicker. I understand that sssd uses caching in both offline and online modes, but I suspect it's trying to use online mode more than is optimal for my situation.

How does sssd decide when to go offline and come back online?
How can I tune how quickly it transitions?

Thanks!

So, "services" in this case is nss or sudo, and if sssd tries to connect to the back end reconnection_retries times, sssd flips into offline mode? – Dylan Martin Jan 31 '17 at 17:51
Yes, if cache_credentials = true. When sssd flips into offline mode he use cache. – Sergey Ovsienko Jan 31 '17 at 19:13
