3 User-Based Authorization System

This chapter describes how to create and manage users and introduces the privilege system.

When created with -db-security authorization option, a database contains a set of database users. Those users are separate from the users managed by the operating system on which Sedna runs. The primary function of the Sedna privilege system is to authenticate a user and to associate that user with privileges on a database object such as DROP, CREATE or QUERY. Users own database objects (for examples, document) and can assign privileges on those objects to other users.
