Environment:

• Ubuntu 16.04
• Python 3.5.2
• azure-cli 0.1.1b3

The help message for az ad sp create-for-rbac says the following for the -n argument:

    --name -n      : A display name or an app id uri. Command will generate one if missing.

I created the SPN using this command.

az ad sp create-for-rbac -n "http://MyGreatSpn" --role Reader --years 2 --password VerySecret

The command returned the following display name instead.

{
  "appId": "2e3c163e-3581-4021-9fef-ff31ef6119ff",
  "displayName": "azure-cli-2017-02-10-22-32-11",
  "name": "http://MyGreatSpn,
  "password": "VerySecret",
  "tenant": "be9c53c3-21fe-4f07-aa2e-b17347fbfa91"
}

I expected the SPN to have a display name of "http://MyGreatSpn" instead of a value assigned by azure-cli. What is the correct way to control this value?
