I am trying to complete a story assignment system for my school newspaper in Google App Engine. It'll track deadlines for writers, allow writers to pick up stories, and give an "at a glance" view of the weeks stories. My partner and I are trying to fully integrate it with our newspapers Google Apps installation. Oh, and we have to use 3 legged Oauth because we don't have Google Apps Premier.
In that endeavor, I stumbled upon Aeoid and was able to follow the instructions to make federated login work. It's very cool!
Where I'm running into trouble is using Oauth to get a list of the users google documents. I have a test page set up here: mustrun.cornellsun.com/test. It is giving me errors - I've copied them at the bottom of this mail. I don't know if this has to do with my consumer secret (should I be using the key I get from google marketplace? or should I be using the key I get from the manage domains page?). Right now I'm using the key I got from the manage domains page
Also complicating this is that the actual appspot domain is mustrun2sun [].appspot[too new can't post more than one link].com, but I set it up in google apps so that only users from my domain can log in and also so that the app is deployed on my domain. (app is deployed as must[]run[].corn[]ellsun[].[]com & everything refers to it as such, even in the manage domains thing.)
I'm using GDClient 2.0 classes so I'm fairly sure that everything should work as planned... i.e. I'm not using the old service stuff or anything. I've used htt[]p:/[]/k[]ing[]yo-bachi.blog[]spot.c[]om/2010/05/gaego[]ogleoauth.ht[]ml as a bit of a template for my Oauth "dance" because the Google examples are out of date & use the old Google data 1.0 library - I think.
The error that I'm getting when I go to my test page is

Also, since this is hard w/o any source code, below is the relevant code:
import gdata.auth
import gdata.gauth
import gdata.docs.client
import gdata.docs.data
import gdata.docs.service
import gdata.alt.appengine
from aeoid import middleware, users
class GetOauthToken(webapp.RequestHandler):

user_id = users.get_current_user().user_id()
saved_request_token = gdata.gauth.AeLoad("tmp_"+user_id)
gdata.gauth.AeDelete ("tmp_" + user_id)
request_token = gdata.gauth.AuthorizeRequestToken(saved_request_token, self.request.uri)
#upgrade the token
access_token = client.GetAccessToken(request_token)
#save the upgraded token
gdata.gauth.AeSave(access_token, user_id)
self.redirect('/test')
class Test(webapp.RequestHandler):

if TOKEN:

client.auth_token = gdata.gauth.AeLoad(users.get_current_user().user_id()) #could try to put back as TOKEN?
self.response.out.write('moo baby')

self.response.headers['Content-Type'] = 'text/plain'
for entry in feed.entry:

else:

self.request.host)
request_token = client.GetOAuthToken(
SETTINGS['SCOPES'], oauth_callback_url, SETTINGS['CONSUMER_KEY'],
consumer_secret=SETTINGS['CONSUMER_SECRET'])
gdata.gauth.AeSave(request_token, "tmp_"+users.get_current_user().user_id())
# Authorize request token
domain = None#'cornellsun.com'
self.redirect(str(request_token.generate_authorization_url(google_apps_domain=domain)))
I've been looking high and low on the web for an answer & I have not been able to find one.
