title: Provisioning Profile 'Valid signing identity not found' error
body: <p>I have an app that is ready for testing on my iPad, and I've created a development provisioning profile, matched up the bundleID and lowered the iOS deployment target.
  However when I downloaded the profile and dragged it into the organizer, it says 'Valid signing identity not found'. I'm pretty sure this has got to do with the certificates in the keychain and private keys (???) however I have no idea how to fix this problem.</p>
  
  <p>Can someone please point me to a tutorial or give me some advice on adding certificates into the keychain without using Xcode; stuff like the 'use for development' button isn't working for me!</p>
  
  <p>Note:
  The only valid Provisioning Profiles are distribution.
  When I try to click 'Renew' Xcode says 'No value was provided for the parameter 'CertificateIDs'. I hope this helps!</p>
