Allows you to authenticate against PAM using OmniAuth.
use OmniAuth:Strategies::PAM
There are no configuration options. It's been tested under Debian 6.0 (Squeeze) and Ruby 1.9.3, but there's no reason why it won't work anywhere which doesn't have PAM correctly configured. Note: The above is assumed for Sinatra, check the OmniAuth docs for Rails, et. al. usage.
Then navigate to '/auth/pam'.
On Debian/Ubuntu you will need the libpam0g-dev package to compile the rpam gem. Others, I don't know.
This strategy only supports Ruby 1.9. Read here about 1.8 support.
