I can reproduce this bug in Vivid as well (evolution-data-server 3.12.9-0ubuntu2).
@Jonathan Yes, when we are authenticating separately with evolution or through Gnome-Online-Accounts, it works. Only time its fails when it tries to authenticate google-contacts through Ubuntu-Online-Acoounts. May be something wrong with google-contacts apikey/token that UOA uses? Also the workaround doesn't work for application which depends on UOA. For example, Ubuntu generates extra binary (syncevolution-provider-uoa) for syncevolution to make it work with UOA. But when following command is executed, SYNCEVOLUTION_DEBUG=1 syncevolution --print-databases --daemon=no loglevel=2 backend=carddav username=uoa:3,google-contacts syncURL=https://www.googleapis.com/.well-known/carddav it gives "Access denied ; Neon error code 1: 403 Forbidden" error. ** Summary changed: - Google contacts authentication problem with U-O-A (Trusty, Unity7) + Google contacts authentication problem with U-O-A (Trusty,Vivid - Unity7) ** Tags added: vivid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1399953 Title: Google contacts authentication problem with U-O-A (Trusty,Vivid - Unity7) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/account-plugins/+bug/1399953/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
