This plugin integrates JWT authentication and automates user creation. The plugin is written for AAF Rapid Connect, but can be used for other providers too.
Here is how this plugin works:
<ol>
<li>Generate a secrete key with command: tr -dc ‘[[:alnum:][:punct:]]’ < /dev/urandom | head -c32 ;echo</li>
<li>Register the key and call back URL http://yoursite.com/wp-json/jwt-auth/v1/callback with your authentication provider.</li>
<li>Specify authentication and user creation parameters. Those marked with * are required.</li>
</ol>

This plugin allows sign in to WordPress using a JSON Web Token (JWT) contained in a HTTP Header that is added by a reverse proxy 
that sits in front of your WordPress deployment.
Authentication and optionally role assignment is handled by claims contained in the JWT.
Verification of the JWT is handled by either:
<ul>
<li>a shared secret key</li>
<li>retrieving a JSON Web Key Set (JWKS) from a configured URL</li>
</ul>
During the login process if the user does not exist an account will be created with a matching role from the JWT.
If the JWT did not contain a role claim then user is created with the role set in the plugin settings (by default this is the subscriber role).
