I have a lot of problems with RADA authentication. When I start my tests
the NAS (a stack of 4 3com 4400 24 port switches in a network of 100
switches) sends access requests to 2 freeradius servers (primary and
secondary) asking for user authentication. All seems to work right (the
radius servers reply requests sending "Login OK" after checking if
username/password = MACaddress/MACaddress are in MySql database) but at
one moment, the NAS sends the Access-Request with username a3Com and
password a3Com. I added account a3Com/a3Com in database, and the radius
servers answer "Login OK: [a3Com]", but the NAS go down with a warning
that sounds like : "The RADIUS Authentication service is not responding".
What is the mistake? Freeradius? 3com 4400 Switch? MySql? Debian? Netwok? Me?

this is NAS request
