Creating ClearPass connector

ClearPass Policy Manager (CCPM) is a network access system that can send information about authenticated users to third party systems, such as a FortiGate or FortiManager. ClearPass connector for FortiManager centralizes updates from ClearPass for all FortiGate devices and leverages the efficient FSSO protocol to apply dynamic policy updates to FortiGate.

You can create multiple ClearPass connectors per ADOM.

Requirements:

• FortiManager version 5.6 or later ADOM

  This example applies to version 6.0 or later ADOMs.

• FortiGate is managed by FortiManager and configured to work with ClearPass
• JSON API is exposed, allowing ClearPass to call it

To configure ClearPass:

1. Log in to ClearPass Policy Manager..
2. Create roles:
   1. Go to Configuration > Identity > Roles.
   2. Click Add.
   3. For the name, enter mytest1.

      FortiManager will get this group as an Active Directory group.

      The Description field is optional.

      

   4. Click Save.
3. Create local users:
   1. Go to Configuration > Identity > Local Users.
   2. Click Add.
   3. Configure the following:
      • Set User ID to test1.
