Sun OpenSSO Enterprise 8.0 Technical Overview

Account Locking

The Authentication Service provides account locking to prevent a user from completing the authentication process after a specified number of failures. OpenSSO Enterprise sends email notifications to administrators when account lockouts occur. OpenSSO Enterprise supports:

Physical Locking.

By default, user accounts are physically unlocked. You can initiate physical locking by typing inactive as the value of the Lockout Attribute Name attribute in the Core Authentication Service. Additionally, the value of the Login Failure Lockout Duration attribute should be set to 0.

physical lock attr name is: inetuserstatus value active/inactive

Memory Locking.

You can configure Memory Locking so that a user account is locked in memory after a specified number of authentication attempts. By changing the Login Failure Lockout Duration attribute to a value greater then 0, the user’s account is then locked in memory for the number of minutes specified and the account is unlocked after the time period elapses.

To figure out the amount of time the lockout will be in effect, the value of the Lockout Duration Multiplier attribute is multiplied by the value of the Login Failure Lockout Duration attribute for subsequent lockout. For example, if the value of Login Failure Lockout Duration is 5 minutes and the value of the Lockout Duration Multiplier is 2, the first time a user is locked out in memory will be 5 minutes. The second time this same user gets locked out in memory the lockout duration will be 10 minutes (5 minutes x 2). The third time this same user gets locked out in memory the lockout duration will be 20 minutes (5 minutes x 2 x 2).

The account locking feature is disabled by default. Account locking activities are also logged. For information on how to enable it, see Enabling Account Lockout in Sun OpenSSO Enterprise 8.0 Administration Guide.


Note –

Only authentication modules that throw an Invalid Password Exception can leverage the Account Locking feature. Out of the box, these include Active Directory, Data Store, HTTP Basic, LDAP, and Membership.
