SAS(R) 9.1.3 Companion for z/OS

System Options under z/OS FILEBLKSIZE(device-type)= System Option 429
an explanatory message in the SAS log. SAS does not attempt to open the data set if the
user ID does not have the proper authorization. However, the auditing requirements for
some installations cause unauthorized access attempts to be sent to the log for that
site’s authorization facility. An attempt to open the data set must actually occur before
a message is sent to the log of the authorization facility. Specify FILEAUTHDEFER for
unauthorized access attempts to be logged with the authorization facility at your site.
The FILEAUTHDEFER option controls the checking of file authorization for external
files and SAS data libraries. However, it only applies to files or libraries which reside in
z/OS data sets. FILEAUTHDEFER does not apply to the processing of HFS files.
FILEAUTHDEFER does not control the authorization checking for z/OS data sets
that a SAS server accesses on behalf of a client. Such third-party authorization
checking is performed regardless of the FILEAUTHDEFER setting, and access failures
are intercepted by SAS rather than resulting in abends or system errors. Nonetheless,
FILEAUTHDEFER governs attempts by a SAS server to access a data set in a manner
not authorized for the ID under which the server is running. However, the unauthorized
access will be logged as having been attempted by the server ID, not the client ID.
