A policy predicate is a logical expression that can be applied to a policy to limit how it is applied to incoming requests or revocations. For example, the following predicate expression specifies that the policy in which it appears can have a different effect for requests or revocations from clients with DNs that include ou=sales,o=acme,c=us:
Type=="client" AND DN=="ou=sales,o=acme,c=us"
