title: "Untrusted App Developer" message when installing enterprise iOS Application
body: <p>I'm developing an enterprise application. When I was testing it in iOS8 beta I saw the following alert view:</p>
  
  <pre><code>Untrusted App Developer
  Do you trust the developer "iPhone Distribution: ---" to run apps on you iPad?
  </code></pre>
  
  <p>It only appears the first time.
  Can I avoid it somehow? And what is it related to?</p>
