Reset Local Admin User on VM using AzureRM Rest api - rest

Question

I'm using the AzureRM rest api to communicate to the hypervisor. One of the things I need to do is to reset the local admin password on a VM, however I can't figure out how to reset it.

Answer 1

We could use the Virtual Machine Extensions REST API to do that. It works correctly for me. Following is my detail test info.
1.We need to get the authorization in the request header
Authorization:Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUz.......
Content-Type:application/json
2.Add the following info in the request body
{
"properties": {
"publisher": "Microsoft.Compute",
"type": "VMAccessAgent",
"typeHandlerVersion": "2.0",
"autoUpgradeMinorVersion": true,
"settings": {
"UserName": "local admin" //your local admin
},
"protectedSettings": {
"Password": "your reset passord" //match the password policy
}
},
"location": "East Asia"
}
Send the http request with Fiddler.
4 . Successfully remote the VM with reset password.
We also can reset our local admin password in the Azure portal.

You can also use the Azure .NET SDK, which has a wrapper for the create or update call.
I tried and ran into an issue where the VM extension request went through fine and was installed successfully, but the password was not updated.
After attaching fiddler, I saw that my dynamic objects for settings and protectedSettings were not getting properly serialized by the library. The solution was to pass a dictionary down to the VirtualMachineExtensions() constructor instead.
Before:
proxy.VirtualMachineExtensions.BeginCreateOrUpdateWithHttpMessagesAsync(
"<resource group>",
"<vm name>",
"<you name it>",
new Microsoft.Azure.Management.Compute.Models.VirtualMachineExtension(
location: "westus",
publisher: "Microsoft.Compute",
virtualMachineExtensionType: "VMAccessAgent",
typeHandlerVersion: "2.0",
autoUpgradeMinorVersion: true,
settings: new
{
UserName: "<username>"
},
protectedSettings: new
{
Password: "<password>"
}));
After:
proxy.VirtualMachineExtensions.BeginCreateOrUpdateWithHttpMessagesAsync(
"<resource group>",
"<vm name>",
"<you name it>",
new Microsoft.Azure.Management.Compute.Models.VirtualMachineExtension(
location: "westus",
publisher: "Microsoft.Compute",
virtualMachineExtensionType: "VMAccessAgent",
typeHandlerVersion: "2.0",
autoUpgradeMinorVersion: true,
settings: new Dictionary<string, string>()
{
{ "UserName", "<username>" }
},
protectedSettings: new Dictionary<string, string>()
{
{"PassWord", "<password>" }
}));
