On receiving users defined in the security database. If authentication is successful the server will allow the application access to any database that it requests and then use the roles and privileges defined in that 4 Chapter 3. The Problem A developer creates a database (and usually an accompanying client application) for installation on servers at remote sites. At such sites it is usual for a person at that site
