Just to follow up on this... I wrote a custom SoupAuth class for OAuth. Instead of calling soup_auth_authenticate() on it, you would instead call a different function that takes the consumer key, consumer secret, token and token secret strings as parameters, which the GNOME Online Accounts API provides. Turns out it was all for naught, because I later realized Google's CalDAV interface currently only supports Basic HTTP authentication. Haven't seen any indication that OAuth support is forthcoming. So that kinda sucks; users will still have to enter a password to access the calendar even if they have a valid access token. But it does mean GOA integration in Evolution is pretty much done for now and I can get back to other priorities. I'll keep my little SoupAuth class around in case the situation with Google's CalDAV interface changes. ___ evolution-hackers mailing list evolution-hackers@gnome.org To change your list options or unsubscribe, visit ... http://mail.gnome.org/mailman/listinfo/evolution-hackers

And I think I have a handle on the mail > side -- just need to extend our CamelSASL framework to handle XOAUTH > from outside of Camel. libgdata's new API implements authentication/authorisation using a GDataAuthorizer interface[1]. At the moment, libgdata has implementations of this interface for ClientLogin (Google's old username/password auth system) and OAuth 1.0. The patch I've got for e-d-s converts the Google Contacts address book backend to use libgdata's ClientLogin authoriser to keep up with libgdata's rampant API breaks. What I've been discussing with davidz is the implementation of some sort of GnomeOnlineAccountsAuthorizer class (in e-d-s' Google Contacts backend?) which implements GDataAuthorizer and just sticks GOA's OAuth 1.0 tokens onto every request. This would work for Google Contacts. > Google Calendars have me stumped, however, since we defer to our > standard CalDAV backend which authenticates with stored passwords from > the keyring.

I guess either the standard CalDAV backend could be modified to use OAuth if the domain name matches “google.com” (or whatever); or the Google Calendar backend could be resurrected with special authentication code, but sharing the CalDAV code with the normal CalDAV backend.

Hi, I do not know much background of OAuth, (to be honest, none at all), thus this is rather a question than answer: CalDAV is using libsoup to connect to the Google's calendar server and what you are dealing with is that you do not know how to tell CalDAV to use OAuth and how to pass it from the UI part to the backend, supposing the libsoup is capable of this OAuth feature? If so, then that might be pretty simple with EClient (on actual git master), just do: a) in e-client-utils.c::e_credentials_authenticate_helper check for which account you are asking credentials and set some key in ECredentials to indicate you are offering OAuth "token" b) in CalDAV backend, in authenticate_user handler, check for the key from a) and pass either user/password or OAuth to libsoup, based on its presence.

Having just started on it this week, so far I'm mostly just concerned with keeping Evolution synchronized with any Google online accounts. But yeah, I was hoping libgdata would make things magically work for address book authentication. And I think I have a handle on the mail side -- just need to extend our CamelSASL framework to handle XOAUTH from outside of Camel. Google Calendars have me stumped, however, since we defer to our standard CalDAV backend which authenticates with stored passwords from the keyring. I'm not sure how to slip in OAuth integration for this one special case. I'm open to suggestions if you have any. ___ evolution-hackers mailing list evolution-hackers@gnome.org To change your list options or unsubscribe, visit ... http://mail.gnome.org/mailman/listinfo/evolution-hackers
