Anonymous Simple Authentication and Security Layer (SASL) Mechanism
K. Zeilenga · 2006
On the Internet, it is common practice to permit anonymous access to various services.Traditionally, this has been done with a plaintext password mechanism using "anonymous" as the user name and using optional trace information, such as an email address, as the password.As plain-text login commands are not permitted in new IETF protocols, a new way to provide anonymous login is needed within the context of the Simple Authentication and Security Layer (SASL) framework.
