Authenticating to REST API with AD authentication enabled

Hi all,

I am trying to authenticate against the REST API with basic authentication but we have NTLM enabled as well as the basic plugin in our environment.  Whenever I do this I am getting a username or password failure and a form to log into TeamCity.

Here is my code:

$teamCityCredential = get-credential
$teamCityHost = "https://teamcity.domain.com/"
$headers = @{
"Content-Type" = "text/plain";
}

$body = "true"
$api = "$($teamCityHost)httpAuth/app/rest/agents/name:my%20agent/authorized"
$response = Invoke-WebRequest -Uri $api -Headers $headers -Method Put -Body $body -Credential $teamCityCredential

When I run without credentials I get an unauthorized message whereas if I push the credentials I am getting a username/password failure so I think the creds are getting through.  I also tried creating the Authorization header in the script and get the same results.

I have seen some examples of using the .Net API to contact TeamCity but want to use pure PowerShell if possible.

Thanks,

Andrew.
