!!! Overview
[{$pagename}] ([GS2]) is defined in [RFC 5801] and describes how to use a [Generic Security Service Application Program Interface] ([GSS-API]) mechanism in the [Simple Authentication and Security Layer] ([SASL]) framework. 

This is done by defining a new SASL mechanism family, called [{$pagename}]. 

The [{$pagename}] offers a number of improvements over the previous "[SASL]/ [GSSAPI]" mechanism: it is more general, uses fewer messages for the authentication phase in some cases, and supports negotiable use of [channel] [binding]. 

Only [GSS-API] mechanisms that support channel binding and [Mutual Authentication] are supported.
