While I've EAP-TTLS w/EAP-MSCHAPv2 working now with ntlm_auth, I'd also like to have EAP-TTLS w/PAP working with ntlm_auth (mostly because the client software I use [securew2] does not save user credentials with mschap, and does save them with pap. And just to offer more options to other clients). Anyway, I tried to do it using these suggestions (after previously my own attempt failed): http://lists.cistron.nl/pipermail/freeradius-users/2008-March/070469.html in radiusd.conf: exec ntlm_auth_pap { wait = yes input_pairs = request shell_escape = yes output = none program = "/usr/bin/ntlm_auth --request-nt-key --domain=MYNET --username=%{User-Name} --password=%{User-Password}" } then in sites-enabled/inner-tunnel: authenticate { Auth-Type PAP { ntlm_auth_pap } Actually I did the same in sites-enabled/default as well to see if it helps (didn't matter, of course). Just, for the record, pap is also in the authorize { } section, listed at the end in that block, as recommended. But.. no luck.. it seems the ntlm_auth stuff is not being called at all, and to be honest I'm not even sure if pap is picking things up. I always end up with this: Wed May 28 15:16:08 2008 : Debug: modsingle[authorize]: calling pap (rlm_pap) for request 5 Wed May 28 15:16:08 2008 : Debug: modsingle[authorize]: returned from pap (rlm_pap) for request 5 Wed May 28 15:16:08 2008 : Debug: ++[pap] returns noop Wed May 28 15:16:08 2008 : Debug: auth: No authenticate method (Auth-Type) configuration found for the request: Rejecting the user Wed May 28 15:16:08 2008 : Debug: auth: Failed to validate the user. Wed May 28 15:16:08 2008 : Auth: Login incorrect: [MYNET\\myuser/xxx] (from client localhost port 0 cli 02-00-00-00-00-01 via TLS tunnel) I used this wpa supplicant config for testing with eapol_test: network={ ssid="mynet-test" key_mgmt=WPA-EAP eap=TTLS pairwise=CCMP TKIP group=CCMP TKIP WEP104 WEP40 phase2="auth=PAP" identity="MYNET\myuser" password="xxx" anonymous_identity="anonymous@identity" } I first tried a different aproach, like putting ntlm_auth_pap in the authorize { } section before pap, and then radius *is* calling ntlm_auth, but then it just goes on and complains about not known the Auth-Type.
