Microsoft (Public) OpenID Setup

warning

Be mindful when configuring public OpenID providers. Any user who authenticates with the provider gains access to your Kasm Workspaces deployment. Kasm group permissions can restrict access to Workspace apps and desktops, but any user of the public authentication provider can still log in to your deployment. Use a private OpenID provider unless you intend to allow 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.
