Permission denied

[peter]

Hi

I'm having permission problems when trying to create a map. This only
occurs on some accounts.

* I authenticate using the ClientLogin and get an authorisation token
back from Google. The behaviour I'm seeing is the same if a CAPTCHA
challenge is issued or not.

* I then use the authorisation token to create a map and I get HTTP
403 returned with the message "Permission denied".

I can't see any difference in format of the requests and authorisation
token whether it succeeds or not. Likewise, it always works on some
accounts and never on others.

Can anyone suggest what is going on here? I'm happy to post keyless
requests and responses should they be needed.

Thanks
Peter.
