Delegated RA entities can have a policy for RA-CA communication. The processing of this policy takes place when a request arrives from a remote RA to the CA (the RA has already accepted the request). However, the policy is run only if the CA policy contains the Apply Policy Attributes (from Entity) module in the receive-request chain. See Section Editing CA Policy Chains.
The RA-CA communication policy contains only the receive-request chain (see Section Policy Chains). The policy can be edited by clicking Edit Policy on the Delegated Registration Authority Entity page.
