Re: eap sim authentication for multiple clients

There is a clear distinction between the two cases.

First case: user record is found in users file:


rad_recv: Access-Request packet from host 192.168.2.1 port 2048, id=1, 
length=215

Second case: user record is not found in users file:


rad_recv: Access-Request packet from host 192.168.2.1 port 2048, id=2, 
length=215

[skipped]

+- entering group authorize {...}

Failed to authenticate the user.

It seems your users file is broken in some way. You need to fix it.

eap sim authentication for multiple clients

2013-06-27 Thread raptor raptor 
Hi,


i have tried with one client and it's success to authenticate and access
internet in wlan
i just try one client and success but when i use another client and it fails

first, i connect with one client and it's success
(until "Finished request 2" in debug log)

and then in next request, i try with different supplicant/client to
authenticate and i have input identitiy (IMSI, RAND, SRES,KC) in to
simtriplets.dat and users also

my simtriplets.dat format
