Intruder detection is the act of detecting actions that attempt to compromise the confidentiality, integrity or availability of a resource. In the context of eDirectory this means you detect false logins and brute force attempts. Normally, when implemented different levels of security are taken into account. Because the impact of a compromised user account is lower than a compromised administrator account there are different restrictive levels.

These settings only apply to user accounts directly under the container. These setting do not flow through.
