With this plugin you can use your own WordPress install to authenticate with a webservice that provides <a href="https://openid.net/connect/" rel="nofollow ugc">OpenID Connect</a> to implement Single-Sign On (SSO) for your users.
The plugin is currently only configured using constants and hooks as follows:
<h3>Define the RSA keys</h3>
If you don’t have keys that you want to use yet, generate them using these commands:
<pre><code>openssl genrsa -out oidc.key 4096
openssl rsa -in oidc.key -pubout -out public.key
</code></pre>
And make them available to the plugin as follows (this needs to be added before WordPress loads):
<pre><code>define( 'OIDC_PUBLIC_KEY', <<<OIDC_PUBLIC_KEY
-----BEGIN PUBLIC KEY-----
...
-----END PUBLIC KEY-----
OIDC_PUBLIC_KEY
);

define( 'OIDC_PRIVATE_KEY', <<<OIDC_PRIVATE_KEY
-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
OIDC_PRIVATE_KEY
);
</code></pre>
Alternatively, you can also put them outside the webroot and load them from the files like this:
<pre><code>define( 'OIDC_PUBLIC_KEY', file_get_contents( '/web-inaccessible/oidc.key' ) );
define( 'OIDC_PRIVATE_KEY', file_get_contents( '/web-inaccessible/private.key' ) );
</code></pre>
<h3>Define the clients</h3>
Define your clients by adding a filter to <code>oidc_registered_clients</code> in a separate plugin file or <code>functions.php</code> of your theme or in a MU-plugin like:
<pre><code>add_filter( 'oidc_registered_clients', 'my_oidc_clients' );
function my_oidc_clients() {
 return array(
 'client_id_random_string' => array(
 'name' => 'The name of the Client',
 'secret' => 'a secret string',
 'redirect_uri' => 'https://example.com/redirect.uri',
 'grant_types' => array( 'authorization_code' ),
 'scope' => 'openid profile',
 ),
 );
}
</code></pre>
<h3>Exclude URL from caching</h3>
<ul>
<li><code>example.com/wp-json/openid-connect/userinfo</code>: We implement caching exclusion measures for this endpoint by setting <code>Cache-Control: 'no-cache'</code> headers and defining the <code>DONOTCACHEPAGE</code> constant. If you have a unique caching configuration, please ensure that you manually exclude this URL from caching.</li>
</ul>
<h3>Github Repo</h3>
You can report any issues you encounter directly on <a href="https://github.com/Automattic/wp-openid-connect-server" rel="nofollow ugc">Github repo: Automattic/wp-openid-connect-server</a>
