Raw message 

Hi Gianluca

We use the raddact table to detect multiple logins. Looking at
https://github.com/GraseHotspot/grase-conf-freeradius/blob/master/freeradius/sites-available/default.grase#L464
we can comment out that line which should prevent the radwtmp file being
written at all. You'll find that file in /etc/freeradius/sites-available/
I'll aim to fix that in the package shortly.

Let us know if that fixes your issue. If it's recently become an issue, I'd
be looking at the volume of users you are getting, and see if that has
increased recently.

Regards

Tim
