title: How do I view the Jenkins server console output on the local filesystem?
body: <p>I'm using the Jenkins Active Directory plug-in and can't log in after several attempts.
  The error message says:</p>
  
  <p><code>If you are a system administrator and suspect this to be a configuration problem, see the server console output for more details.</code></p>
  
  <p>Where can I find the server console output (on the local filesystem)?</p>
  
  <p>I presume that it is accessible from the Jenkins web pages, but since I can't log in, that's not much use. I <em>can</em> log in to the (Windows) server where Jenkins is installed - where are they on the server?</p>
