5.2.10 Setting User Accounts (Settings Tab)
Using the User Accounts button in the Settings tab, you can change the default admin login
password and set up admin and user accounts.
Before you start configuring the xStack Storage, we recommend that you use the Accounts
button to:

Enhance the security of the xStack Storage Management Center by changing the default
login password for the admin user.

Set up the other admins and/or users who will be using the xStack Storage Management
Center to manage the xStack Storage.
Thereafter, you can use the User Accounts button in the Settings tab to edit user accounts
in case you need to change a user’s login password or delete user accounts for users who will
no longer be managing the xStack Storage system. For more information about adding,
modifying, and deleting user accounts, see section 2.3.

tab and Table 5-2 describes the settings.

and terminology.
