Use this page to enable or disable the TrustPointDNCustomRule policy, an example of a custom plug-in policy you can develop by using the application programming interfaces (APIs) that Oracle Certificate Authority provides. See Oracle Certificate Authority Administrator's Guide for information about writing a custom policy plug-in.
When enabled, the TrustPointDNCustomRule policy checks the DN in every certificate request against all of the CA and subCA certificates' DNs in the certificate chain. If the DN specified in the certificate request matches any CA's DN, then Oracle Certificate Authority rejects the request. (The certificate chain is an ordered list of certificates containing an end entity certificate and its corresponding CA certificates.)
