23.2.3 A Walkthrough of DCE Application Authentication Using
GSSAPI
This section describes the process by which applications that manage network
communications without RPC can use GSSAPI and DCE Security to authenticate the
applications with which they communicate. It continues from the end of "A
Walkthrough of User Authentication", see Section 23.2.1.
In peer-to-peer communications, the application that establishes the secure connection
is the context initiator or simply initiator. The context initiator is like a DCE RPC
client. The application that accepts the secure connection is the context acceptor or
simply acceptor. The context acceptor is like a DCE RPC server.
The peer applications establish a secure connection in the following way. The
numbers of the stages described correspond to callouts in The following figure.
