rfc.4505 - Anonymous Simple Authentication and Security Layer (SASL) Mechanism
08.06.2006
Abstract:
On the Internet, it is common practice to permit anonymous access to
various services. Traditionally, this has been done with a plain-
text 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.
