User Summary Openfire 3.7.1

Wondering what the list is? When I display it (/user-summary.jsp), it shows around 800 users, most of who are offline (only 2 online).

I was trying to get a list of current users. I opted to copy the users who were in groups and made a list from those.

A quick check indicates the users who show up in the user summary for the most part are not in the groups list I produced from browsing groups.

We use LDAP auth and have a filter requirement for auth - wondering if /user-summary.jsp are former users (how does this explain the 2 I noticed who were online, and also happen to be in groups - and who are not former)?

Thanks for any insight. We are using Oracle as the DB.
