When you use AUTHDOMAIN=, you must specify the server host in the LIBNAME statement.
However, the authentication domain references credentials so that you do not need
to specify the USER= and PASSWORD=
LIBNAME statement options.
AUTHDOMAIN=SPDS
An administrator optionally creates an authentication domain definition at the same
time that they are creating user definitions with the User
Manager in
SAS Management Console. The authentication domain is associated with one or more login metadata objects.
These objects provide access to the server and are resolved by the
SASSPDS engine calling the
SAS Metadata Server and returning the authentication credentials.
The authentication domain and the associated login definition must be stored in a
metadata repository, and
the metadata server must be running in order to resolve the metadata object specification.
