Hello gentlemen's,
After one week search the web for a solution, i come to this maling list. I
have to set up a mac-based authentication system (pretty simple) with HP
procurve swtichs. I have see lot of tutorials, buy a book, download more, but
it still don't work (access-request denied).
I hope somebody can look at my basic problem a few minute.
User is reconized (found at line X), but freeradius don't know how to
interprete the password (I think).
I have see that the CHAP-password attribute send by the client (HP Procurve
2800), is not the same heach time. Is it normal (I don't think). The switch
look like he is well configured (running-config in attachement).
In attachement, you will find initialisation of freeradius (radius_init), an
acces-request from the client (acces-request), the entry of my test user
(users), and the running config of the HP Procurve.
I hope somebody know this problem.
Kind regards
Sébastien Serre
