python django集成cas验证系统

* 在MIDDLEWARE_CLASSES 中添加CAS的配置: 
 
  'django_cas.middleware.CASMiddleware'
 
* 在AUTHENTICATION_BACKENDS 中添加CAS的配置：
 
  'django_cas.backends.CASBackend'
 
 注意在django1.6 中默认是没有AuthenticationMiddleware 的配置项的，需要手动添加,
 并添加该行配置:
 
  'django.contrib.auth.backends.ModelBackend',
 
* 配置CAS_SERVER_URL： 该地址为cas验证服务器的地址，必须配置
