Authenticating to FTL Server

FTL server can be configured with one or more authentication providers, allowing FTL server to understand basic authentication, mTLS authentication, oauth2 authentication, or all three. When accepting incoming connections, FTL server can accept different authentication modes for different connections, as long as an appropriate auth provider is configured.

In addition, each client and FTL server must be configured to authenticate itself to FTL servers. When making a connection to an FTL server, the client or server must choose exactly one of the possible authentication modes (basic, mTLS, or oauth2). For FTL server, this configuration (for outgoing connections) is independent of the auth provider configuration (for incoming connections).
