can not initiate sim, no RAND1 attribute [eap] ERROR - Default EAP type sim failed in initiate [eap]

[ken.farrington]

Hi All,
I really do try to read the forums in full before I post, but I have seen much
out there on this, but just cant find out why this is happening.
Please see below.

The only think I dont have is "sim_files" entry in the sites-enabled/default, as
I assume this is now covered in the radiusd.conf file.

Also, in the simtriplets files at the bottom, I have tried the entries with a 1
at the beiging of the IMSI, and without and with the word SIM there also.

On packet captures over the air, I get
P1 - eap identity request
P2 - eap identity response
P3 - eap-failure

So I beleive the radius server is not sending an eap-start <module> and is my
configuration issue.

Could anyone be so kind to help me please?
