If you specify a value
for the AUTHID= option, the table name is qualified as
authid.tablename before
any SQL code is passed to the DBMS. If you do not specify AUTHID=,
the table name is not qualified before being passed to the DBMS and
the DBMS uses your user ID as the qualifier. If you specify AUTHID=
in a
SAS/SHARE LIBNAME statement, the ID of the active server is the
default ID.
