If you are using other Communardo apps like Metadata for Confluence and User Profiles for Confluence (Microsoft Attributes Sync) more sophisticated integrations are possible. For example you can have a CQL navigation element that lists all content that is relevant to users working in the same office as the current user. In order to do so the CQL query has to include the corresponding fields form the other two apps. The following example shows the basic structure:
metadatafield.Site:upc.currentUser.Location
Here the field "Site" is managed in Metadata for Confluence, while the values of that field are stored in the field "Location" provided by User Profiles for Confluence (and most likely this will be synchronized from the user directory).
