Overview
The bedework carddav server can deliver personal addressbooks stored within the system or act as a gateway to other sources of directory information. It can deliver both V3 and V4 vcards.
Directory handlers.
The carddav server delivers content out of a hierarchy of information. The shape of that hierarchy is determined by the configuration. Different parts of the hierarchy are typically delivered by different directory handlers. For example, as configured, the "/directory/users" branch is a gateway to the enterprise user directory - delivering vcards based on the account information.
