Have watched them - they're great, thank you. But yes, doesn't help. I can't even sign up, so don't get anywhere. I'm starting to suspect its an setting on my google app domain regarding federated sign in, but can't find the issue.

Hmmm. I remember seeing something on the web about OAuth being different for Google Apps accounts and normal free personal accounts. Have you tried creating a new "plainold" GMail account, and testing everything with that?

Have you even detected which software throws oauth_error=3, to get an idea of what it is supposed to mean? Anything in your log files?

@Martin H. Bramwell: so you've taken all this time to look into somebody else's problem, and recorded videos and all. That's what open source should be about, great work! At least they should honor you with a special badge, "dedicated" or something similar.

I wouldn't take it to that extreme. In fact open source is about sharing the benefits of one's own research. Thenon's problem coincided with my own need, and I wanted to be sure I knew how to avoid the oauth_error=3 sinkhole. I also saw a real lack of a proper explanation on how to do Google OAuth, so I made the videos. I tried to make the kind of howto video I myself look for : a thorough explanation in less than 10 minutes. Sure, a special badge would be nice! Of course getting your one up tick of recognition is also nice. Thanks! Well, I got one anyway. :-(

Agreed - thanks for the help! Well this is the error the debug log shows: openerp.addons.auth_oauth.controllers.main: OAuth2: access denied, redirect to main page in case a valid session exists, without setting cookies. Haven't tried plain ol gmail yet (agree its a good idea) because to be honest, if I can't get it working for the apps domain, then it's not useful to me.

I do not have an apps domain or I would try it out, to see if it is indeed the case that there are differences. Perhaps someone else can confirm. I don't have time right now.

hey, I suppose you have tried from a different browser?
