  That's not a simple thing... EAP-SIM is weird and bizarre.  Historically it hasn't been well tested in FreeRADIUS.

  The good news is that I've fixed things up in the v3.0.x branch, which will soon by 3.0.16.  So you should really use that branch from github.

  You can then add this in raddb/mods-config/files/authorize:

bob     EAP-SIM-Ki := 0xabcdef...

  Replace the hex digits with the actual value of the Ki key.

  And you can run radeapclient with the following input file as "sim.txt"

User-Name := "bob"
EAP-Code = Response
EAP-Type-Identity = "bob"
EAP-SIM-Ki = 0xabcdef...

  With the same Ki, of course.

  Then do:

$ radeapclient -f sim.txt localhost  auth testing123

  and it should work.

  Older versions of radeapclient required the SIM triplets, which meant you could only test it once.  That's annoying.
