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.
