Re: eap sim authorization problem

20 Jun 2013

      Hi, IIiya
i'm sorry my posting above is about one client

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
