Proxmox Virtual Environment is an open source server virtualization management solution based on QEMU/KVM and LXC. You can manage virtual machines, containers, highly available clusters, storage and networks with an integrated, easy-to-use web interface or via CLI. Proxmox VE code is licensed under the GNU Affero General Public License, version 3. The project is developed and maintained by Proxmox Server Solutions GmbH.
After configuring the source in Proxmox, any user that logs in to Proxmox for the first time automatically gets an user named `<authentik username>@<pve realm name>`. In this example,
authentik user `bob` will get an user named `bob@authentik` in Proxmox. You can then assign Permissions as normally in Proxmox. You can also pre-create the users in Proxmox if you want
the user to be able to perform actions immediately after first login.
There is no way to directly trigger an OpenID Connect login in Proxmox, but if you set the source as 'default', it will be automatically selected on the Proxmox login screen.
