[devnull]

Hi,

I'm authing about 60 3com 4400 switch with mysql. Everithing goes ok until the switch sends a
particular request to the server. This is the request:

rad_recv: Access-Request packet from host 10.10.0.219:2049, id=57, length=87
        User-Name = "a3Com"

Going to the next request


This is OK, but switch says "Radius server authentication is not responding"
The strange thing is the userame a3Com that i've never seen in any switch configuration.
Is something related to including dictionary.3Com in dictionary file ?

I've googled a lot and searched in 3Com knowledge base but can't find anything.
