If a firewall closes the connection between Crowd and OpenLDAP, Crowd should reconnect to OpenLDAP. (I guess this applies to other LDAP directories as well.)

Crowd should also have a keep alive option to prevent the connection from being terminated. This functionality is important when it's not possible to configure the firewall session TTL high enough.
