Types

type AuthConfig 

type AuthConfig struct {
	// Scope defines the scope for the authentication plugin.
	// - 1 means passwords only
	// - 2 means public keys only
	// - 4 means keyboard interactive only
	// - 8 means TLS certificates only
	// you can combine the scopes, for example 3 means password and public key, 5 password and keyboard
	// interactive and so on

	// If enabled the client and the server automatically negotiate mTLS for
	// transport authentication. This ensures that only the original client will
	// be allowed to connect to the server, and all other connections will be
	// rejected. The client will also refuse to connect to any server that isn't
	// the original instance started by the client.
