SSSD has a cache update feature that can renew the cache prior to expiration to reduce the cache-miss penalty on oft-requested entries. We originally opted to leave it disabled by default (since it increases load slightly on the LDAP server).
However, I think the performance gains on the client side are well-worth the small load increase on the server side (which would still be much lower than the load without SSSD at all).
I propose that we should change the default value for {{{entry_cache_nowait_percentage}}} to be 50% (so entries would automatically refresh out-of-band when they were queried after half of their expiration time has passed).
