The Base DN (Distinguished Name) defines the 'starting point' where ClearPass begins searching the Active Directory tree. If an organization stores Users in OU=Users,DC=corp and Computers in OU=Workstations,DC=corp, setting the Base DN specifically to the Users OU prevents ClearPass from seeing any objects in the Workstations OU. To fix this, the administrator should set the Base DN higher in the hierarchy (e.g., DC=corp) and use search filters to find the specific objects.

When an OnGuard agent finishes its scan, it sends the results to ClearPass. If the status has changed (e.g., from 'Healthy' to 'Unhealthy'), ClearPass evaluates its Enforcement Policy and selects a profile that includes a CoA (Change of Authorization) action. ClearPass sends this Disconnect-Request to the switch (NAD), which drops the client session. The device's supplicant immediately reconnects, triggering a new authentication that places the user in the correct, updated role.

In a sponsor-approved guest workflow, the guest user typically needs to identify who is responsible for their access. Requiring a guest to manually type in an employee's email address is prone to errors. By implementing a drop-down list of valid sponsors, ClearPass simplifies the experience. The administrator can populate this list with specific individuals or departments, ensuring that the guest selects a legitimate sponsor and that the approval request is routed to the correct person immediately.

ClearPass and EMM/MDM integration provides 'Closed-Loop' security. When ClearPass identifies a 'Stolen' device status (either via its own database or a real-time check), it can use a Context Server Action to signal the EMM server. The EMM server, which has deep administrative control over the device OS, can then execute high-level security commands such as Remote Wipe (deleting all data) or displaying a 'Lock Screen' message to the person holding the device.

Health Checks are the core mechanism of OnGuard. These checks look for specific attributes on the endpoint, such as whether the antivirus is up-to-date, if the OS firewall is enabled, or if unauthorized applications (like peer-to-peer software) are running. The result of these checks is a 'Posture Token' (Healthy, Unhealthy, or Unknown) that ClearPass uses to make enforcement decisions.
