Hello, I have successfully installed osTicket v1.15.3.1 on Apache 2.4 (Ubuntu).
After some reading I configured Apache to authenticate with my Azure AD via SAML/SSO. I can confirm that authentication is successful, after it is done I see my email (userPrincipalName) in Apache logs.
I have installed and enabled auth-passthru ("HTTP Passthru Authentication") plugin.
However, even after Apache successfully authenticates with Azure AD, I see "Guest User" in right top corner of osTicket and cannot progress - it thinks I am not authenticated.
What am I missing here? Any help will be appreciated.
