How to send Permanent ID request in EAP-SIM method?

[lambertdev]

Hello, 
      As we know,EAP-SIM specifacation defines three kinds of identity.But
when I read the source code of "rlm_eap_sim.c",freeradius only sends
FULL_AUTH_ID_REQUEST. 
      i.e.In function "eap_sim_sendstart",there is 
  
      newvp = paircreate(ATTRIBUTE_EAP_SIM_BASE+PW_EAP_SIM_FULLAUTH_ID_REQ,  
PW_TYPE_OCTETS); 

      For sending eap permanent id request to peer,I tried to modify this
sentence to: 

       newvp =
paircreate(ATTRIBUTE_EAP_SIM_BASE+PW_EAP_SIM_PERMANENT_ID_REQ,  
PW_TYPE_OCTETS); 
      
     and compiled it successfully. 
    
      But when I tried to test the server,with the command below: 

      radeapclient -x localhost auth testing123 <eapsim-in.txt 
      
      the server will return:

 I wonder why did this happen?How should I do if I want send a PERMANENT_ID
request to the server？Thank you！！
