Gets a value indicating whether the membership user is locked out and unable to be validated.
Assembly: System.Web.ApplicationServices (in System.Web.ApplicationServices.dll)
Users can also be locked out if you use the GetPassword or ResetPassword overload that accepts a password answer and the number of bad answers entered by the user reaches the Membership.MaxInvalidPasswordAttemptswithin the Membership.PasswordAttemptWindow.
To set this property to false and let the user try to log in again, you can use the UnlockUser method.
