17.8. Authentication

A careful study of the authentication problem shows that it should be done during reception of commands and/or jobs from a remote user and/or spooler. At this time the following must be done:

1. The received command must be checked for consistency, and the remote user and host must be determined.

2. The remote user and host must be authenticated.

3. The command and/or spooling operation must be carried out.

4. The results must be returned to the remote system.
