For security purposes, users attempting to log in to the PXE must be authenticated. The PXE supports the access using one of the following authentication mechanisms:
By default, the PXE is configured for local authentication. If you stay with this method, you do not need to do anything other than create user profiles for each authorized user.
If you prefer external authentication, you must provide the PXE with information about the external authentication server.
If both local and external authentication is needed, create user profiles on the PXE in addition to providing the external authentication server data.
When configured for external authentication, all PXE users must have an account on the external authentication server. Local‑authentication-only users will have no access to the PXE except for the admin, who always can access the PXE.
