Following the documentation on the OsTicket site, I've installed OSTicket 1.8 on IIS (Server 2022) with PHP 8.1 and MySql 8
All the preq checks passed on the installation and the site works fine to all intensive purposes but having installing the OAuth plug which I selected during the download of OSTicket I cannot get the Azure authentication to work.
I followed the documentation to setup SSO with Azure (https://docs.osticket.com/en/latest/OAuth2/Microsoft%20Authentication%20(SSO)%20Guide.html), I've triple checked my setup and it's exactly setup as directed in the documentation, it works in so much as it arrives at a page post successful authentication to the AzureAd, but doesn't login to my OSTicket portal. This is the case for both the end user portal and the ticket management portal aspect.
Are there any diagnostic checks I can perform or other items that need configuring?
