Data source signons
You add signons to data source connections so that users do not have to enter database credentials when they run reports.
When you create a signon, you specify the users and groups that can access the signon. The user ID and password that make up the signon must already be defined in the database.
You can modify an existing signon if the credentials used to log on to the database change, or if you want to change who can use the signon.
For data source configurations that require each user to have their own signon, it can be unwieldy to administer them all. For information on how users can manage their own data source credentials, see Manage Your Own Data Source Credentials.
