Features Not Available for Database Authentication
Some of the features that other authentication strategies provide are not available with database authentication, including:
- A single user-authentication method that is valid for Siebel Business Applications and other applications 
- User self-registration (typically used with customer applications) 
- External delegated administration of users (typically used with partner applications) 
- Creation of users on the database server by adding users from the Administration - User screen in the Siebel application.
