This version implements the server side OAuth "Bearer" token verification against an external authorization server. It aims at supporting both the php-oauth service and the Google service.
Install this code in the directory user_oauth in the apps directory of
your Owncloud installation.
This module needs an external dependency to verify the OAuth tokens at the OAuth authorization server. A script can be used to install this dependency:
$ cd /path/to/owncloud/apps/user_oauth
$ cd 3rdparty
$ sh fetch_3rdparty_libs.sh
You need Git installed on your server to fetch the 3rd party dependency.
You can enable the user_oauth app after login with the admin account. Go
to Settings, then Apps and finally select the OAuth module from the list
of modules, select it and press the Enable button.
There currently is only one configuration parameter: the Token Info Endpoint. For quick tests, one can use the playground environment, installed using this script located at https://frko.surfnetlabs.nl/workshop/.
For the "workshop" installation the Token Info Endpoint would be
https://frko.surfnetlabs.nl/workshop/php-oauth/tokeninfo.php
For Google the Token Info Endpoint is:
https://www.googleapis.com/oauth2/v1/tokeninfo
You can set this endpoint by going to Settings, then Admin and then under
the section head OAuth configure the URL.
An application needs to use the OAuth service to retrieve an access token to
use this with the OAuth enabled WebDAV endpoint. The endpoint, assuming you
run the service on https://www.example.org/owncloud, note odav instead of
webdav:
https://www.example.org/owncloud/remote.php/odav/<FILE.EXT>
So, in order for an application to work it needs to obtain an access token from the OAuth authorization server that you configured as a Token Info Endpoint in the OAuth app configuration in Owncloud. If you used the playground mentioned above that would mean using the following URLs:
https://frko.surfnetlabs.nl/workshop/php-oauth/authorize.php
https://frko.surfnetlabs.nl/workshop/php-oauth/token.php
For Google this will probably be some Google URL. You also need to register the app at Google. In the playground environment you can also register an OAuth client yourself.
Template applications for both Android and iOS are available that implement OAuth 2.0 and can be used to modify the Owncloud Mobile Apps.
So far, the Owncloud Mobile Apps have not been updated to support OAuth 2.0.
The app was tested with version 4.5.4 of Owncloud.
