# Basic Installation
First, you'll need a few prerequisites.
* the latest libopkele from http://kin.klever.net/libopkele (C++ implementation of important OpenID functions)
* libsqlite from http://www.sqlite.org (SQLite C libs)
Next, run:
./configure
or
./configure --help
to see additional options that can be specified.
Next, run:
make
su root
make install
Make sure that the file /tmp/mod_auth_openid.db is owned by the user running Apache.
You can do this by (assuming www-data is the user running apache):
su root
touch /tmp/mod_auth_openid.db
chown www-data /tmp/mod_auth_openid.db
Or you can specify an alternate location that the user running apache has write
privieges on (see the docs for the AuthOpenIDDBLocation directive on the homepage).
# Usage
In either a Directory, Location, or File directive in httpd.conf, place the following directive:
AuthType OpenID
Require valid-user
There are also additional, optional directives. See the homepage for a list and docs.
The user's identity URL will be available in the REMOTE_USER cgi environment variable after
authentication.
See [the project page](http://findingscience.com/mod_auth_openid) for more information.
