Re: mapping Google Apps to Appengine error 1000

[Alexis]

I had this issue a week ago:

Make sure the domain you want to add is a primary domain or an alias of a primary domain.

GAE does not support mapping to a secondary domain.

If you map to an alias domain note that you will not be able to send mails with an admin sender from this domain.

(Ex: if you want to send emails from no-r...@my-alias-domain.com)

This particular domain is an alias to primary domain, I can ever create mapping for names different from www. There is a thread on this issue here with more details: https://productforums.google.com/d/topic/apps/JuvJrTMJmAs/discussion
