[[!meta title="Configuring Client-Side Certificate Authentication on Apache"]]
-While it's certainly possible to configure client-side certificate authentication on Apache using the built-in SSL module alone, it's much easier if you use the Apache modules developed for the [scripts.mit.edu](http://scripts.mit.edu) project.

## Installing the modules
-If you're using Ubuntu, Evan Broder has packaged the scripts.mit.edu modules for all current Ubuntu releases in a PPA.
+If you're using Ubuntu, Evan Broder has packaged the scripts.mit.edu modules for all current Ubuntu releases (through 11.x) in a PPA.
The [PPA homepage](https://launchpad.net/~broder/+archive/scripts-http-mods) includes instructions on how to install the PPA on your system, but if you're on Ubuntu Karmic or later, you can just run:
# aptitude install libapache2-mod-auth-sslcert libapache2-mod-authz-afsgroup
-You'll also need a working AFS client and the Athena client certificate CA. Both of these can be most easily configured by [installing Debathena](http://debathena.mit.edu/install). You can install any Debathena flavor you'd like, but `debathena-standard` flavor should include everything you need.

-Once you've done that, the instructions in the [scripts.mit.edu FAQ](http://scripts.mit.edu/faq/15) on configuring certificate access through `.htaccess` files should work.
