Has anyone experienced a problem when trying to monitor for the LOGIN or LOGOUT events using LDAP event monitoring against an eDirectory tree?

Using v8.8, anytime the event occurs on a monitored server, the event is sent and my app receives it. But in an tree, I get lots of other types of events, but I never get either of these two events.

Is this a known issue? Anyone else experience it? Any way around it?

Thanks much...
