In databases, a connection is always stateful, which means that when a connection is established, it must be authenticated.
Configure your database user name and password on the NetScaler appliance. For example, if you have a user John configured on the database, you need to configure the user John on the ADC too. Adding database user names and passwords on the ADC adds them to the nsconfig file.
Names are case sensitive.
The ADC uses these user credentials to authenticate the clients, and then authenticate the server connections with the database servers.
