Good day everyone,

Hitting a wall in making MSFT OAuth to work (account login). Followed the guide from https://docs.osticket.com/en/latest/OAuth2/Microsoft%20Authentication%20(SSO)%20Guide.html

I was able to get into MSFT login page and input my account credentials and agree to a prompt to access my account data then 404 error.

Below is my configuration file:

azureuser@TICKETSVR01:~$ a2enmod rewrite
Module rewrite already enabled

Local admin user is working without issues. I think the same might be true with normal user login.

Below is a snippet of error in osticket.access.log inside /var/log/apache2:

Have not tried configuring emails yet.

Thanks in advance everyone!
