SYS
A level of authentication security for programs such as admind or sadmind.
At this security level, the server accepts the original user and group
identities from the client system and uses them as the identities for the
authorization checks. There is no checking to be sure that the UID of the user represents the same user on the server system. That is, it is
assumed the administrator has made the UIDs and GIDs consistent on all systems in
the network. Checks occur to verify that the user has permission to execute the
request.
