Internet password lock and ldap

We use Domino 8.5.2 FP2 as a LDAP source for Connections 3.0.1. The documentation states that Internet password lockout is enforced only for the HTTP protocol but then goes on to state “However, Internet password lockout can be used for Web access if the password that is used for authentication is stored on an LDAP server”.

Has anyone used Inet lockout to a Domino LDAP server?
