Figure 5 Validating Access Requests

The items in this table, identified by letters appearing in parentheses in Figure 5, explain the

process:

The OSS NFS client user ID is used as the search index for the list of OSS NFS users previously defined

by the SCF ADD USER commands.

Does the search find this user ID in the list of OSS NFS users?B

Is the server’s NULL-ALIAS-OK attribute TRUE or FALSE?C

Is the nobody client user ID (-2) in the list?D

Map the OSS NFS client found in the list (which could be nobody) to its corresponding OS user ID.E

Does the corresponding OS user ID = 255,255?F

Is the server’s ROOT-USER-OK attribute TRUE or FALSE?G

Process the access request for this user.H

Reject this access request with the access violation code NFSERR_ACCESS.I
