expiration during which warnings will commence. Password expiration does not disable or lock out the account. Use the following attributes to set the password expiration policy: • MinPasswordAge Specifies the minimum number of days that must elapse before a user can change a password. MinPasswordAge values range from 0 to 999. The default value is zero. Setting this parameter to a non-zero value discourages users from rapidly changing a password in order to circumvent the password history setting to select a recently-used password. The MinPasswordAge policy is not enforced when an administrator changes the password for another user. • MaxPasswordAge Specifies the maximum number of days that can elapse before a password must be changed, and is also known as the password expiration period. MaxPasswordAge values in range from 0 to 999. The default value is 0. Setting this parameter to zero disables password expiration. • Warning Specifies the number of days prior to password expiration that a warning about password expiration is displayed. Warning values range from 0 to 999. The default value is 0 days. NOTE: When MaxPasswordAge is set to a non-zero value, MinPasswordAge and Warning must be set to a value that is less than or equal to MaxPasswordAge. Upgrade and downgrade considerations for password management If you are upgrading from a 5.3.x environment to 6.0.0 or later, the existing password databases do not contain the state information that implements password expiration. So, when the password expiration policy is first set after an upgrade to 6.0.0 or later, any users who have not changed their password will have their password expiration period set to the maximum password expiration period. You must explicitly define the password expiration for users who have not performed a password change subsequent to the upgrade. IMPORTANT: You cannot upgrade your switch from Fabric OS 5.3.0 directly to 6.2.0. You first have to upgrade to 6.0.0, then to 6.1.0, and then to 6.2.0. For example: • March 1st-Using Fabric OS 5.3.x release. User A changes her password. • April 1-Upgrade to 6.0.0 (or later). • May 1-User B changes his password. • June 1-The password configuration parameter MaxPasswordAge is set to 90 days. User A's password will expire on September 1. User B's password will expire on August 1. Account lockout policy The account lockout policy disables a user account when that user exceeds a specified number of failed login attempts. The policy is enforced across all user accounts. You can configure this policy to keep the account locked until explicit administrative action is taken to unlock it, or the locked account can be automatically unlocked after a specified period. Administrators can unlock a locked account at any time. A failed login attempt counter is maintained for each user on each switch instance. The counters for all user accounts are reset to zero when the account lockout policy is enabled. The counter for an individual account is reset to zero when the account is unlocked after a LockoutDuration period expires. The admin account can also have the lockout policy enabled on it. The admin account lockout policy is disabled by default and uses the same lockout threshold as the other roles. It can be automatically unlocked after the lockout duration passes or when it is manually unlocked by either a user account that has a securityAdmin or other Admin role.
