403 Forbidden Accessing admin section with admin user credentials about youtube-direct HOT 4 OPEN

I really have not idea why this would be happening. YTD just relies on the 
standard App Engine administrator restrictions to protect URLs under /admin, 
and if you're supplying the same credentials when logging into /admin as you 
used when deploying your App Engine instance it definitely should work.

Could you confirm that this is still an issue that you're experiencing?

Hi api.jeffy,

I think the issue is when you login using a non-google email/account.

Our company is using Google email, docs, etc. So when I login to the appengine 
I login using this address https://appengine.google.com/a/[COMPANY NAME] then 
using my company email [NAME]@[COMPANY NAME].com to login.

Then I create my application and make sure my account has permission (which 
happens automatically because I created using this account).

Then when I go to the YTD admin and try to login using my company account, it 
returns the 403 error.

What I have to do in the app engine administration is send an invite to my 
Google email account ([NAME]@gmail.com) and then use that login to access the 
YTD admin. I shouldn't need to do this, I should be able to access the YTD 
admin using my company account credentials because it has the correct access to 
the application.

I had a similar issue with my installation.  

I have a CNAME alias for my YTD direct installation (eg., ytd.mydomain.com).  
When accessed the admin pages at ytd.mydomain.com/admin I received the 403 
error message.  

The problem was resolved when I edited the web.xml file and removed lines 95-97:
     <user-data-constraint>
      <transport-guarantee>CONFIDENTIAL</transport-guarantee>
    </user-data-constraint>

I suspect the issue may be with the CNAME and the appspot.com SSL certificate.
