A lockout policy specifies the conditions under which a user's vCenter Single Sign On account is locked. In vSphere 5.1, you log in to the Single Sign On server rather than in to individual vCenter Server systems. This means that the lockout policy applies to users who access vCenter Server by logging in to the vSphere Web Client. You can edit the lockout policy.

A vCenter Single Sign On user account might be locked when a user exceeds the allowed number of failed attempts to log in. The lockout policy allows you to specify the maximum number of failed login attempts and how much time can elapse between failures. The policy also specifies how much time must elapse before the account is automatically unlocked.
