Creating a policy to dynamically modify a resource based on the SCIM resource type

Given an attribute defined in multiple resource types, modify the attribute differently depending on the resource type. In particular, this policy focuses on the retrieve action and changes the cn attribute to one value for the Users resource type and to another value for the Devices resource type.

Steps

  1. In the Policy Editor, go to Policies in the left pane and then click Policies along the top.

  2. From the menu, select Add Policy.

  3. For the name, replace Untitled with Modify cn attribute based on the resource type.

  4. Click the next to Applies to.

  5. Click Add definitions and targets, or drag from Components and add the retrieve action.

  6. Set Combining Algorithm to Unless one decision is deny, the decision will be permit.

    You should have a screen similar to the following one for the policy so far.
