title: Xcode 4.6 - "Valid signing identity not found" for Distribution provisioning profile
body: <p>I'm examining the process of submitting an app to the App Store and I'm having some kind of trouble here. I've been following <a href="http://developer.apple.com/library/ios/#documentation/ToolsLanguages/Conceptual/YourFirstAppStoreSubmission/SubmitYourApp/SubmitYourApp.html#//apple_ref/doc/uid/TP40011375-CH7-SW1" rel="nofollow noreferrer">this tutorial</a>.</p>
  
  <p>I've created a Distribution Provisioning Profile, which I downloaded and added to Window - Organizer - Devices dragged in 'Provisioning Profiles' under the Library heading in the sidebar. What I see there is this:</p>
  
  <p><img src="https://i.stack.imgur.com/OT3al.png" alt="Here is an image of it."></p>
  
  <p>I've tried revoking all my certificates and adding them once again to my Keychain Access, but it didn't help. Even after refreshing the provisioning profiles in Xcode.</p>
  
  <p>Also, I've read that this happens often if I change the machine I'm working on, but this is not my case. I've developed the app on the same Mac, I'm on right now.</p>
  
  <p>I'm willing to provide more information to help reach to a solution to this problem if needed. Thanks for your help in advance.</p>
