In this tutorial we’ll install the Debian Linux 9 (squeeze), Apache 2 with mpm-itk (to run each web as a isolated user),...
OpenID authentication with the mod_auth_openid Apache module
Ástþór IPmod_auth_openid is an authentication module for the Apache 2 webserver. It handles the functions of an OpenID consumer as specified in the OpenID 2.0 specification.
After a user authenticates themselves, the user’s identity will be available in the REMOTE_USER variable. A cookie named open_id_session_id is saved to maintain each user’s session.
1. Install the module
apt-get install libapache2-mod-auth-openid
2. Enable the module
a2enmod authopenid
3. You can now add the line below to any Directory, Location or File directive in the virtual host configuration or a .htaccess file .
AuthOpenIDEnabled On
4. Restart Apache
/etc/init.d/apache2 restart

Tried it on Ubuntu Maverick, and the Apache module is not created. What’s missing is (from the original doc at http://findingscience.com/mod_auth_openid/):
Verify that the module has been enabled in your ”httpd.conf”:
# note that the path to your module might be different
LoadModule authopenid_module /usr/lib/apache2/modules/mod_auth_openid.so(in my case, this was the only line in httpd.conf). Then everything works like a charm.
