I use example/00-authentication.go to test this case.
My config.json is as follow:
[root@controller examples]# cat config.json
{
 "Host": "http://172.16.197.131:35357/v2.0",
 "Username": "admin",
 "Password": "aaaaaa",
 "ProjectID": "1d8837c5fcef4892951397df97661f97",
 "ProjectName": "admin",
  "Container": "",
 "ImageRegion": "default_cluster"
}

When i use 'go run 00-authentication.go setup.go' to test the authenticate function. It return failed.

config: &{Host:http://172.16.197.131:35357/v2.0 Username:admin Password:aaaaaa ProjectID:1d8837c5fcef4892951397df97661f97 ProjectName:admin Container: ImageRegion:default_cluster Debug:false}
