RadiusClient Bug ?

Hello everybody !!!

I have a Mk 3.2 with MAC Authentication on Wirelless Interface, with one radius server.

In this cenario, everything works fine, without any problem, but
when I add a second radius to RadiusList and a Client send a Connect,
if the primary radius is down/unreacheable, the packets of authentication flow to radius2,
at this point OK, i see the counts on Status Tab, increment on a Requests e Accepts fields,
the Radius Server ( linux box), was accept authentication but the MAC appear on RegTable, for a few seconds
and then disapear. So the process go to begin, and packets are sending again to radius.

When the radius1 go up, the autentication will be back OK.

Anyone know if this is bug or what a hell is this.

Regards

Alex
