Running a version of the system connected to ldap, the cache takes a long time to populate. I think once the cache has expired (6 minutes) it tries to connect and gets the following error:
00000DD6 2018-08-06 15:47:25.189 19597 22832 "cached connection invalid (Can't contact LDAP server), creating a new connection"
00000DD7 2018-08-06 15:47:25.189 19597 22832 "connecting to ldap:...."
So it keeps rebuilding the cache. Does the connection need to be kept alive to prevent this?
