Unspecified flags.
Authentication type uses password, specified and stored in the system, i.e. not in an external authentication service (such as LDAP catalog).
Password is used with authentication type UserLoginTypes.Internal.
Authentication type has login (account name). If login is absent then authentication is unavailable using login/password or login only (NTLM/Kerberos), meaning either auth is forbidden, or its custom made without login in non-default controller methods.
Login is absent for authentication type UserLoginTypes.Forbidden.
