The anonymous authentication scheme is used when you do not want to challenge users for credentials. My webMethods Server honors an anonymous request and establishes a session with the server as a special Guest user, but the user is never prompted for credentials. The anonymous authentication scheme is used for unprotected areas of the server that might be public facing and do not contain sensitive information. By associating the request with a session and a user ID of Guest, an administrator can extend behaviors of anonymous access by controlling permissions of the Guest user. Guest is one of the default users installed as part of the system directory service. It is also possible to track session activity of anonymous users for reporting requirements.
