title: TF.exe git permission login failing in pipeline yet correctly logs in locally
body: <p>I am trying to automate a process using TF.exe within an Azure DevOps pipeline. I am trying to run:</p>
  <pre><code>.\TF.exe git permission /collection:MyOrganization /login:MyPersonalAccessToken /noprompt
  </code></pre>
  <p>which correctly signs me in locally. However, when I run that same command in a PowerShell script that's running in an Azure Pipeline, it fails with</p>
  <pre><code>TF30063: You are not authorized to access MyOrganization
  </code></pre>
  <p>I've tried this without the PAT as well, instead using direct login credentials. Still, local login works completely fine, but in pipeline it will not go through with the same error.</p>
  <p>I cannot use System.AccessToken at the moment, because we are first testing the automated workflow against a different organization (I am administrator in both). Is using TF.exe via pipeline only supported when logging in with OAuth Token?</p>
