11.2. Default Evaluators
Red Hat Certificate System provides four default evaluators. The following entries are listed by default in the
CS.cfg file:
accessEvaluator.impl.group.class=com.netscape.cms.evaluators.GroupAccessEvaluator accessEvaluator.impl.ipaddress.class=com.netscape.cms.evaluators.IPAddressAccessEvaluator accessEvaluator.impl.user.class=com.netscape.cms.evaluators.UserAccessEvaluator accessEvaluator.impl.user_origreq.class=com.netscape.cms.evaluators.UserOrigReqAccessEvaluator
The
group access evaluator evaluates the group membership properties of a user. For example, in the following enrollment profile entry, only the CA agents are allowed to go through enrollment with that profile:
authz.acl=group="Certificate Manager Agents"
The
ipaddress access evaluator evaluates the IP address of the requesting subject. For example, in the following enrollment profile entry, only the host bearing the specified IP address can go through enrollment with that profile:
authz.acl=ipaddress="a.b.c.d.e.f"
The
user access evaluator evaluates the user ID for exact match. For example, in the following enrollment profile entry, only the user matching the listed user is allowed to go through enrollment with that profile:
authz.acl=user="bob"
The
user_origreq access evaluator evaluates the authenticated user against a previous matching request for equality. This special evaluator is designed specifically for renewal purpose to make sure the user requesting the renewal is the same user that owns the original request. For example, in the following renewal enrollment profile entry, the UID of the authenticated user must match the UID of the user requesting the renewal:
authz.acl=user_origreq="auth_token.uid"
New evaluators can be written in the current framework and can be registered through the CS console. The default evaluators can be used as templates to expand and customize into more targeted plug-ins.
