| (1) 什么是SASL和Cyrus SASL
SASL (Simple Authentication Security Layer) is an Internet standards-track method for remote computers to authenticate. The Cyrus SASL library makes supporting various SASL mechanisms easy for both client and server writers.
The Cyrus project is the implementation of an enterprise mail system by the Carnegie Mellon University Computing Services Department. We are interested in scalable, easy to administer systems.
(2) Cyrus SASL组成部分
SASL是一个胶合(glue)库，通过这个库把应用层和形式多样的认证系统整合在一起。这有点类似于 PAM，但是后者是认证方式，决定什么人可以访问什么服务，而SASL是认证过程，侧重于信任建立过程，这个过程可以调用PAM来建立信任关系。 |
