title: How can I add private key to the distribution certificate?
body: <p>Well, I've got my Developer Certificate linked with it's private key. Works Fine.</p>
  
  <p>I've downloaded my iOS Profile of distributor, but it says Valid signing identity not found.</p>
  
  <p>So I checked my certificates, and exactly, my developer certificate it's linked with its private key but not my distribution certificate. How can I link/add my private keys to this certificate!? </p>
  
  <p>Will this solve the problem "Valid Signing identity not found"?</p>
