Updating my review because I made contact with Adaclare and it turns out I happened to purchase this plugin just as they were doing a server migration, so I failed to get my license key, but the person I spoke to was able to get it to me quickly. I tested the plugin and it worked great, though FWIW, be aware this is a way to enable OIDC authentication to the admin panel only, not WHMCS itself (the user side). Works great for that purpose.
