RFC 2222 SASL (Simple Authentication and Security Layer)

The Cyrus SASL (Simple Authentication and Security Layer) SASL is the Simple Authentication and Security Layer, a method for adding authentication support to connection-based protocols. To use SASL, a protocol includes a command for identifying and authenticating a user to a server and for optionally negotiating protection of subsequent protocol interactions. If its use is negotiated, a security layer is inserted between the protocol and the connection.
