NTLM认证在Windows的各种登陆方式都要用到，例如telnet登录，IIS访问，Proxy访问。糖果NTLM认证解决的是Proxy的NTLM认证, 让你用编程的方式通过NTLM认证.
当使用微软的 ISA Server用作防火墙软件时, ISA采用的默认认证方式就是NTLM. 它的好处是 与域用户系统 合为一体, 降低管理工作量.
NTLM认证过程较为复杂,需要 客户端 与服务器进行三次握手,例如:

认证过程中并不传递用户密码,而且每次认证信息都不一样(通过一整套加密算法),以防止通过监听网络获得帐户信息.
糖果NTLM认证模块能够让你以编程的方式通过NTLM认证, 可以用当前的Windows帐户进行NTLM认证,也可以指定 用户名, 密码, 域名 进行认证.
