When you use SAS Federation Server LIBNAME engine, you can connect only to data sources
and locations as defined through the
server administration. A non-administrative user must connect by using a
DSN definition.
A DSN definition configures the authorization that is enforced for data access. The
available
authorization process depends on the
data source. Third-party databases enforce data
source security and can also be configured for SAS Federation Server authorization. A DSN
definition for SAS data sets cannot use both SAS passwords and SAS Federation Server
authorization.
