VMS Help DCE, Overview and Contents of Kit, CDS Server Kit  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The CDS Server Kit provides the naming services necessary for DCE
  clients to locate DCE server applications.

  The CDS Server kit includes the following:

     - CDS server (cdsd)

     - Global Directory Agent (gdad)

       The Global Directory Agent (GDA) lets you link multiple CDS
       namespaces using the Internet Domain Name System (DNS), X.500,
       or LDAP.
