Dan,

The other question I had was, I suppose you see the AUDIT_USER_LOGIN
event type which triggers the prelude event (in audisp-prelude.c). I
would think that the matching AUDIT_USER_LOGOUT would be what you want
right?

Can you find these events with ausearch like this?:

# ausearch -ts today -i -m USER_LOGIN
...and...
#ausearch -ts today -i -m USER_LOGOUT
