This property is used in conjunction with the
ij.password
property to authenticate a connection. If authentication is not active, these
properties are ignored.
When you supply a username, you need to be aware of the database schema. When
you connect using ij.user, the default database schema applied
to all SQL statements is the same as the user ID provided, even if the schema
does not exist. Use the SET SCHEMA statement to change the default when the
schema does not match the username. Alternately, you can fully qualify the
database objects referred to in the SQL statements. If no user is specified, no
SET SCHEMA statement has been issued, or SQL statements do not include the
schema name, all database objects are assumed to be under the APP schema.
