authentication for custom web application with mod_auth_openidc

I have a basic web application which runs on apache 2.2 and doesn't have any authentication. The site content is a static webpage.
Our small organization is currently working on implementing mod_auth_openidc for all the websites.
I wanted to implement mod_auth_openidc authentication on top of basic static web application.

How can I achieve it?
I am newbie to apache configuration and mod_auth_openidc. I Googled around for some articles to implement it but I couldn't find any. I have created a static account for my application on Oauth2 server.

Can someone point me in right direction on how to enable authentication for my static web page application with mod_auth_openidc and mod_proxy configuration?

Solution

There are examples in the README on the Github project pages: https://github.com/zmartzone/mod_auth_openidc. Assuming the static webpages lives on /example, in your specific (PingFederate) example it would be something like:

OIDCProviderMetadataURL https://<pingfederate-host>:9031/.well-known/openid-configuration

OIDCClientID <client-id-as-registered-with-pingfederate>
OIDCClientSecret <client-secret-as-registered-with-pingfederate>

OIDCRedirectURI https://<your-apache-host>/example/redirect_uri/
OIDCCryptoPassphrase <password>
OIDCScope "openid email profile"

<Location /example/>
   AuthType openid-connect
   Require valid-user
</Location>

A complete working example based on the OPs environment:
