  Don't use PAM.  It's intended for applications to do user authentication... once.

  Maybe they've fixed it, but PAM used to leak memory like crazy when FreeRADIUS used it for repeated authentication.

  And whatever PAM can do for authentication... FreeRADIUS can do better.  And simpler.  And more controlled.

  PAM stands for "pluggable authentication modules".  Well, FreeRADIUS is an authentication server.  And FreeRADIUS has pluggable modules.  And FreeRADIUS has "unlang', and a configuration which is infinitely more flexible than PAM.

  The only reason to use PAM is when you need to use a proprietary authentication plugin that is only supplied via PAM.  And even then, it's only good for PAP authentication.

  PAM doesn't do CHAP, MS-CHAP, EAP, or any other authentication method.

  Don't use PAM.
