Is it possible to use Single Sign On against an AD user source when running a project on a Linux client? We have a Linux box setup to use AD for authentication but running a project with SSO enabled just displays the client login screen. If we enter a valid AD username/password the login works. So, it seems we are having an issue with SSO only.

Thanks

The current AD/SSO implementation only supports Windows; we’re using the [`NTSystem`](https://docs.oracle.com/javase/9/docs/api/com/sun/security/auth/module/NTSystem.html) class to retrieve domain and user information.
