[Feat]: External Authentication Support

Description

It would be nice if at-least the admin panel has support for external authentication protocols like LDAP, OAuth, etc. to be able to integrate it with an existing authentication management solution.

Suggested Solution

The option to add external authentication providers such that one can use them to log into the admin user interface instead of using the username / password. That would mean that the users can choose between different solutions for the authentication process (username/password, OAuth, LDAP, ...).

Alternatives

An alternative (or addition) could be the option to disable authentication entirely, such that one can put the admin panel behind a proxy which then manages the authentication process.
