Once upon a time Karl Denninger shaped the electrons to say...

Ok.

Right - at lease unless/until we implement the RFE for a keyword to
handle dynamic IPs in filters. (Personally I really want to see that.)

>Now I set this up in Choicenet, and arrange to have the RADIUS server return

>Choicenet loads the profile properly.

Ok.

>HOWEVER, it appears that the first user who disconncets from the PM3

That shouldn't happen.

User A logs in.
Filter is downloaded.
User B logs in, users same filter - no new download.
User A logs out.
User C logs in, same filter.
User C logs out.
User B logs out.
Now the filter is removed, as there is no longer a user.

If you are seeing this:
User A logs in.
Filter is downloaded.
User B logs in, users same filter - no new download.
User A logs out.
Filter is deleted - B now no longer has a filter.

Then that sounds like a problem. If you show B's interface is the filter
gone? It may be removed from the filter table, but I don't believe it
is removed from the interface.
