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