title: IOS Enterprise Distribution Through OTA
body: <p>We have build an enterprise iPad App and now we want to give it to our employees. Initially when testing, we used ad-hoc distribution collecting all the test device's UDID and then creating the profile.</p>
  
  <p>Now going live we want this app to be deployed in a secured web server and send the link to our employees, so that they enter the username and password before accessing the link.</p>
  
  <p>There are around 500+ devices we need to install this iPad App. Do i need to collect all the UDID and then deploy the <code>.ipa</code> file, because Apple documentation says:</p>
  
  <blockquote>
    <p>Create an enterprise distribution provisioning profile that authorizes devices to use apps you’ve signed.</p>
  </blockquote>
  
  <p>If not that way, do the user needs to install the <code>profile.mobileprovision</code> file and then install the <code>.ipa</code> file?</p>
  
  <p>We are still unable to decide how to deploy our app because of this issue. We would like to avoid the app approval process because it App handles a lot of sensitive data.</p>
  
  <p>Can some one help me on this, how to do a OTA deployment for enterprise Apps?</p>
