UniqueSubjectNameConstraints Rule

The rule named
UniqueSubjectNameConstraints
automatically creates this rule during installation. By default, the rule is configured
as follows:
• The rule is disabled; for the rule to be effective, it must be enabled and
configured appropriately.
• The certificate requests are checked for subject name uniqueness after agents
process the requests for approval—if you're using manual enrollment and
deferred requests.
• The certificate requests are checked for Key Usage extension.
• The predicate expression is left blank so that the rule is applied to all certificate
enrollment and renewal requests processed by the server.
For details on individual parameters defined in the rule, see Table 3-12 on
page 120. You need to review this rule and make the changes appropriate for your
PKI setup. For instructions, see section "Step 2. Modify Existing Policy Rules" in
Chapter 18, "Setting Up Policies" of CMS Installation and Setup Guide. For
instructions on adding additional instances, see section "Step 4. Add New Policy
Rules" in the same chapter.
