Using EXEC authentication sources
Hello, I'm trying to test something different in my environment. I read that you can use external authenticators using EXEC. I have tried a basic setup and am running into a problem. I'm not super clear on what the logs are trying to tell me. I feel like the documents I'm reading must be outdated or wrong like many of the website out there. I am simply trying to use a PHP script to return Accept; no matter what is called. Just to test this out. *auth.php contents:*
<?PHP echo "Accept"; ?>
Here is my run. You can see an attempt to connect from my device:

I feel like I must have the Executing script in the wrong location maybe? I am running using TTLS-PAP on the client(ignoring the certificate on the clients end) and it gives me an authentication failure. Any insight would be greatly appreciated. Thanks for reading.

You can't just return "accept' when the client is using EAP. You MUST allow the full EAP conversation to run to completion.

Put the accept into the inner-tunnel virtual server. It will work for TTLS + PAP, but not for TTLS + MS-CHAP, or PEAP. Alan DeKok.
Sorry, things are still busy around here. I did not catch that, thank you! I must have edited the wrong file by accident. For the most part things are working great. I am only struggling with one last thing; I am trying to pass the variable for the devices mac address to the script. I am able to collect the username, IP, and their entered pap password perfectly fine. It's just the MacAddr that appears to be blank every time. I thought I was referencing it properly using Calling-Station-Id.. authorize { update control { Auth-Type := `/usr/bin/php -f /etc/freeradius/auth.php '%{User-Name}' '%{User-Password}' '%{Client-IP-Address}' '%{Calling-Station-Id}'` } } A side question I have as well. Do you happen to know of a way to pass these parameters securely? or a way to prevent Injection attacks using this execution method?

I thought I was referencing it properly using Calling-Station-Id..
As always, read the debug output to see where Calling-Station-ID shows up.
authorize { update control { Auth-Type := `/usr/bin/php -f /etc/freeradius/auth.php '%{User-Name}' '%{User-Password}' '%{Client-IP-Address}' '%{Calling-Station-Id}'` } }

Don't exec a program where anything can read the program arguments. Use an interpreted module like rlm_perl or rlm_pyhthon Alan DeKok.
The Calling-Station-ID shows up in the outer portion, eap & "default", but not the inner-tunnel. I just don't understand how I'm supposed to set a custom variable to pass to the inner tunnel for use like this. I'll have to look at the python module when I have the free time, sounds much nicer than what I'm being told to do.. I'm required to use PHP for this job, so I can't just go with the python module unless it was warranted unfortunately. I've expressed my concerns about the security of this method, but they do not care and want it done this way. Their argument is that the server will be locked down with hardware only access once it is completed. My task is simply to collect the user login and device identity, passing it onto their secondary system for processing, then it will respond with Ok or Fail.

You don't. You read "man unlang", which tells you how to reference an outer attribute from the inner-tunnel. Instead of Calling-Station-Id do outer.request:Calling-Station-Id There examples of this kind of thing all through the default configuration files, including "inner-tunnel".

Exec also has performance issues. But if they prefer PHP to Python, they don't care about that either. Alan DeKok.
