SAS 9.4 Guide to Metadata-Bound Libraries, Second Edition

This document is intended for administrators who want SAS to always enforce its metadata-layer permission requirements before providing access to SAS data. Metadata-bound libraries provide enhanced protection for Base SAS data (SAS data sets and SAS views).

In general, only administrators who set up and maintain metadata-bound libraries need to know the information that this document contains. However, in order to access metadata-bound data, a connection to the metadata server is required. So a user who makes a direct request (for example, through a LIBNAME statement) does have to facilitate that connection. See Metadata Server Connection Options.
