<DIV>Hello,</DIV>
<DIV> </DIV>
<DIV>I am developing a PAM module for radius server. </DIV>
<DIV>The radius server is configured to use PAM auth.</DIV>
<DIV>It reads /etc/pam.d/radiusd and loads it on receiving auth request.</DIV>
<DIV> </DIV>
<DIV>The PAM module talks to external Authentication server and sometimes gets back "Challenge Respose".</DIV>
<DIV>How can this be returned back to radius server from pam_sm_authenticate from my PAM module ?</DIV>
<DIV> </DIV>
<DIV>Please note that this is different than what pam_radius_auth.c does. </DIV>
<DIV>pam_radius_auth.c talks to radius directly via network</DIV>
<DIV>where as my module directly gets loaded by Radius.</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>Why should not there be a way to return "Challenge Respose" </DIV>
<DIV>from linux PAM back to it's loader ?</DIV>
<DIV>Can this possible linux limitation be overcome by radius calling another exported function for </DIV>
<DIV>PAM module covering all scenarios including "Challenge Response" ?</DIV>
<DIV>Where should I look into in the freeradius codebase, if I were to</DIV>
<DIV>add that functionality ?</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>with best regards,</DIV>
