configuring the AAA basic setup, you create users and groups. You first create
a user account for each person who will authenticate via the NetScaler
appliance. If you are using local authentication controlled by the NetScaler
appliance itself, you create local user accounts and assign passwords to each
of those accounts.
You also create
user accounts on the NetScaler appliance if you are using an external
authentication server. In this case, however, each user account must exactly
match an account for that user on the external authentication server, and you
do not assign passwords to the user accounts that you create on the NetScaler.
The external authentication server manages the passwords for users that
authenticate with the external authentication server.
If you are using
an external authentication server, you can still create local user accounts on
the NetScaler appliance if, for example, you want to allow temporary users
(such as visitors) to log in but do not want to create entries for those users
on the authentication server. You assign a password to each local user account,
just as you would if you were using local authentication for all user accounts.
account must be bound to policies for authentication and authorization. To
simplify this task, you can create one or more groups and assign user accounts
to them. You can then bind policies to groups instead of individual user
