[diego at gigadata.it]

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"
        User-Password = "a3Com"
        NAS-Port-Type = Virtual
        NAS-IP-Address = 10.10.0.219
        Service-Type = Administrative-User
        Framed-MTU = 1024
        Message-Authenticator = 0xebe1ebfa3372940ad96d932c10457ff8

modcall: group authorize returns ok for request 84

Going to the next request


This is OK, but switch says "The RADIUS Authentication service 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.
