EAP-sim using freeradius

[Siddharth Katragadda]

Hi Matthew
Thanks for the suggestion.  I  tried by changing the EAP-Sim-IMSI to  User-Name
-
but I still get the  eap_sim: ERROR: EAP-SIM-RAND1 not found
Although the  passwd file now says:  [passwd] = ok

So it looks like passwd file was able to find the User-Name in
simtriplets.dat, so it should have extracted the  EAP-SIM-RAND1 etc from it
right?

I've attached the debug log, passwd and simtriplets.dat

Btw, I did have 10 fields in the simtriplets.dat (delimited by colon). Why
did you find only 4??

Thanks
Sid
