7.5. Creating Rules

Rules determine what certificate object is published in what location. Rules work independently, not in tandem. A certificate or CRL that is being published is matched against every rule. Any rule which it matches is activated. In this way, the same certificate or CRL can be published to a file, to an Online Certificate Status Manager, and to an LDAP directory by matching a file-based rule, an OCSP rule, and matching a directory-based rule.

Rules can be set for each object type: CA certificates, CRLs, user certificates, and cross-pair certificates. The rules can be more detailed for different kinds of certificates or different kinds of CRLs.

The rule first determines if the object matches by matching the type and predicate set up in the rule with the object. Where matching objects are published is determined by the publisher and mapper associated with the rule.

Rules are created for each type of certificate the Certificate Manager issues.

Modify publishing rules by doing the following:

Table 7.3, “Predicate Expressions” lists the predicates that can be used to identify CRL issuing points and delta CRLs and certificate profiles.
