  • Accounts and Passwords
    • Password strength and expiry
    • Forced password change
    • Account blocking after authentication failures
    • Deactivation of unused accounts
  • Login Page
    • Appearance of the login page
    • Legal banner messages
  • UI Security page
    • Prevent Cross Site Framing

Configuring these settings is described in the following sections.

For example, if the password expiry is set to 90 days and the user does not change the password in that period, you can select if the account must be locked after 90 days. The default is Yes.
    If Password Expiry Period is set to Never, then the Password Expiry Warning and Lock Accounts After Password Expiry fields are automatically disabled as they are not applicable.

Blocking of the system account

In the following scenario, the system user account can be locked.

  • Account blocking is enabled (the default).
  • Automatic account unblocking is disabled (not the default).
  • A user repeatedly attempts to log in unsuccessfully to the UI as the system user.
    An administrator is required to log in to the system and unblock the account.

A user might be blocked on a cluster member, if for example, they used incorrect credentials more than the permitted number of times, or did not log into that member for a sufficiently long period that their account was deactivated. They are only blocked on that cluster member. They are not blocked on the other members of the cluster, and can continue to use the cluster as before.
