MediaWiki Radius Authentication Extension – RadiusAuthPlugin

Posted on Updated on

Here is an extension / plugin for mediawiki to authenticate against a Radius server. I couldn’t find one anywhere else, which is surprising. I can’t believe I am the first person to want to do this. Anyway, this is just bare bones, but it works for an internal mediawiki setup.

First, get Pure PHP radius class 1.2.2 from This does the actual radius authentication. Put radius.class.php in wiki/extensions/ (assuming wiki is your mediawiki install). There is probably a better place to put it, but I was setting this up for internal use and wanted to get it working quickly.

Next, create wiki/extensions/RadiusAuthPlugin.php. Make sure you fill in RADIUS_SERVER, SHARED_SECRET, and NAS_IP_ADDRESS with your actual information.  Lastly, update your LocalSetup.php.

You can find the RadiusAuthPlugin.php and the part to add to LocalSetup.php in this gist:

    […] so I searched for integrating MediaWiki with a Radius system and found only this blog telling about what I was looking for. I just went through it and realized this was the first […]

    I’m happy that my Pure PHP radius class is used for the MediaWiki project ;-)

    If you need to log some stuff, have also a look at my Syslog class, which is a pure PHP syslog device implementation following the RFC 3164 rules.

    Any chance there is an update for this to work in Mediawiki 1.18? It seems to be broken.

    Thanks in advance,

      Nevermind, issue was my fat fingering. Plugin works perfectly in 1.18.

      Nice work and thanks again.

    Think we can get this script to send accounting information to the rad server?

    Excellent, worked like a charm on Debian 6.0.2 and Mediawiki 1.15.5 (straight from the repositories).

    Hello! I filled SHARED_SECRET and NAS_IP_ADDRESS, but why It told me “Parse error: syntax error, unexpected T_STRING in /www/web/default/extensions/RadiusAuthPlugin.php on line 34″ ?

      They should both be in quotes, is a quote missing? Without seeing your code I can’t know for sure, but that would be my first guess
