interactive users, but the machine principal is not. The Security Validation Service
performs the processing necessary so that other daemon processes on the machine appear
to be running with the machine’s identity.
The Security Validation Service periodically refreshes the ticket-granting ticket for the
machine’s principal. A DCE client machine must have a valid ticket-granting ticket in
order for a principal to use DCE services. The Security Validation Service also exports
the interface that assures a Security client that it is actually contacting the real Security
server when the client requests a ticket-granting ticket from the Security server.
3.1.4 Audit Service Cient Programs
There are no Audit service client programs. The clients of this service are the server
processes of the DCE services that use auditing, for example, the Security Service’s secd
daemon.
3.1.5 CDSClient Programs
The DCE client runs the following CDS processes:
• The CDS advertiser, the cdsadv process, does the following:
— Allows applications to locate and communicate with cdsd servers
— Starts any needed CDS clerks (cdsclerk)
— Creates the cache shared by local CDS clerks
• The cdsclerk is an interface between CDS client applications and CDS servers. A
clerk must exist on every machine that runs a CDS client application. One cdsclerk
process runs for each DCE principal on a machine that accesses CDS. The CDS
clerk handles requests from client applications to a server and caches the results
returned by the server. Because the results of the server request are cached, the clerk
does not have to go repeatedly to the server for the same information. All CDS
clerks on a machine share one cache. One clerk can serve multople client
applications running on the same machine.
3.1.6 DTSClient Programs
The DCE client runs the following DTS processes:
• The dtsd daemon is set to be a client or a server. On a client machine, dtsd
synchronizes the local clock.
• The DCE control program (dcecp) for the management and maintenance of the DTS
software. Optionally, also the dtscp program. See Section 3.3 for descriptions of
