title: iOS Configuration Profile Expiration
body: <p>We are building iOS OTA Enrollment system in our IT.
  After reading Apple docs, i would not find reference how to set an expiration date on the Configuration Profile installed on the device.</p>
  
  <p>My motivation is to create expiration date on profiles that i am going to install based on the device owner (they have to login before i install it)</p>
  
  <p>Is there a way to control how long the Configuration Profile is valid for?</p>
