title: Can't subscribe to any YouTube channels - Why?
body: <p>I've attempted to subscribe to several YouTube channels and it never works. I get the following:</p>
  
  <p><strong>Google Accounts
  We are sorry, but you do not have access to this service. Please contact your domain administrator for access.</strong></p>
  
  <p>I am the domain administrator. I've checked all the setting and can't locate what could be stopping the subscription. Eventually, I want to get my own channel and write code to get at subscription data, but I can't even seem to get through the front door as a user. What am I missing?</p>
