Description:

SASL is the Simple Authentication and Security Layer (as defined by RFC 2222).
It provides a system for adding plugable authenticating support to
connection-based protocols. The SASL Extension for PHP makes the Cyrus SASL
library functions available to PHP. It aims to provide a 1-to-1 wrapper around
the SASL library to provide the greatest amount of implementation flexibility.
To that end, it is possible to build both a client-side and server-side SASL
implementation entirely in PHP.
