CVR Channel

The CVR channel allows you to flag an attribute in a data store (such as eDirectory) with a reset policy. If the value of that specific attribute is changed, the CVR channel resets the value as per the policy defined in the CVR Channel object.

The CVR channel may be used to maintain critical system settings or enforce organizational policies. For example, if your organization has a policy prohibiting security equivalence, you can create a CVR Channel object that automatically resets the Security Equals attribute to a null value.

IMPORTANT: The CVR channel must be used in conjunction with a notification filter. To optimize event processing, the notification filter should be configured to filter only those events that the CVR channel can act on. For a sample configuration, see the Novell Nsure Audit Administration Guide.

CVR Channel Driver

The CVR driver is lgdcvr.*.

When the CVR channel driver receives an event, it looks at the event’s Text2 field to determine if the logged attribute matches the attribute defined in the CVR object. If the CVR driver does not find a matching attribute in the event’s Text2 field, it then looks in the Text1 field.

If the contents of the Text2 or Text1 field match the attribute defined in the CVR object, the driver looks in the remaining Text field to find the object to which the attribute belongs. It then locates the object in eDirectory and applies the Reset Value defined in the CVR object.

NOTE: All NSS, traditional file system, eDirectory, and NetWare events store the event’s attribute in the Text2 field and the object in the Text1 field.

The reset process is very fast. Typically, an attribute is reset the instant it is saved. In fact, in the administrative interface, it simply appears that the change cannot be saved.
