Datastore admin error with simpleauth

[Paul Ceccato]

Is anyone using simpleauth able to access the datastore admin function to backup/restore the datastore contents?

I get a 500 error...

This appengine bug report indicates its an authentication issue, i'm using simplauth for authentication.

"This looks to be a problem because you are using non-default authentication scheme.

Are you using user service/Google Accounts API for authentication of users inside your application? If not, consider changing your authentication method.

If you are, then you'll need to setup a custom domain and access the datastore admin via:
https://ah-builtin-python-bundle-dot-<YOUR APPLICATION VIA YOUR CUSTOM DOMAIN>
so that the correct authentication cookies can be used."
