Hi Experts,
I am testing EAP-SIM/EAP-AKA on Freeradius version-4 by reading the IMSI,
RAND, SRAND etc. from the rlm_passwd module password file which was working
in Version 3, but I am stuck with some attribute errors in version 4.
I believe that Version-4 has changed the attribute on EAP-SIM/EAP-AKA,
however, I have no idea how to map the attribute to make it works like
version-3.
I was trying to compare the dictionary file attribute between V3 and V4 but
still confusing.
here is a passwd format in v3 --> *"format =
"*User-Name:EAP-Sim-RAND1:EAP-Sim-SRES1:EAP-Sim-KC1:EAP-Sim-RAND2:EAP-Sim-SRES2:EAP-Sim-KC2:EAP-Sim-RAND3:EAP-Sim-SRES3:EAP-Sim-KC3:"*
*Can anyone advise the passwd format in version4?*
