Microsoft (Public) OpenID Setup

Warning

Be mindful when configuring OpenID providers that are public. Any user that can successfully authenticate with the provider will have access to your deployment of Kasm Workspaces. While access to Kasm Workspace apps and desktops can be resitricted with Kasm group permissions, any user of the public authentication provider would still be able to login to your deployment of Kasm. It is recommended to use a private OpenID provider unless your intention is to allow authentictioned access to all users of the OpenID platform provider.

This guide walks through a basic setup allowing Microsoft users to authenticate with your Kasm deployment.
