The Facebook integration in Horde is deprecated, this is for historical purposes only
++Configuring Horde 4 for Facebook integration Horde's Facebook integration requires some setup on Facebook in order to get it to working. A Facebook application must be created for each Horde installation. The following are the steps that are required in order to get this working. - Create the application. This is done at http://facebook.com/developers - Under the Website section of the configuration, you need to add the url to your services/facebook page. So, if your horde install is at http://example.com/horde, then your Site URL setting should be *http:*example.com/horde/services/facebook/ *. You also need to enter the Site Domain setting. In this example, it would be *example.com//. - Take note of the Application ID and the Application Secret values. You will need to enter these in Horde's API Keys configuration section. - Once those values are entered into Horde's configuration, users will be able to validate the application via Horde's Facebook Integration preference page.
