Proxmox VE stores user attributes in /etc/pve/user.cfg
.
Passwords are not stored here; users are instead associated with the
authentication realms described below.
Therefore, a user is often internally identified by their username and
realm in the form <userid>@<realm>
.
Each user entry in this file contains the following information:
When you disable or delete a user, or if the expiry date set is in the past, this user will not be able to log in to new sessions or start new tasks. All tasks which have already been started by this user (for example, terminal sessions) will not be terminated automatically by any such event.
