Crowd uses the term 'directory', or 'user directory', to refer to a store of information about a user. Typically, a directory will hold your username, name, password, email address, and so on. Your Crowd administrator can define one or more directories internally in Crowd or connect one or more external directories to Crowd. The external directory may be a corporate directory such as Microsoft's Active Directory. To learn more about Crowd's directory management, please refer to the Crowd Administration Guide.
