mini-oidc is an extremely basic OIDC provider which can be used with the incus command line.
It doesn't use web authentication and instead just automatically approves any authentication request.
Usage:
mini-oidc <port> [<user-file>]
By default, it will authenticate everyone as unknown, but this can be overridden by writing the username to be returned in the file named in the 2nd
(optional) argument. This effectively allows scripting a variety of users without having to deal with actual login.
