When effective

NoteAfter you save an Access Deny form, active requestor sessions on the current node that are associated with that rule are immediately updated. Requestors at other nodes in a cluster are updated when the next system pulse occurs on their node.

OldIn Version 4, changes to an Access Deny rule affected only those requestors who logged in after the change. Active requestors were not affected.

Example

Assume an application includes classes named Data-Refund-Basic, Data-Refund-Silver, and Data-Refund-Gold, all derived from the Data-Refund- abstract class, and two access roles named Refund:Worker and Refund:Super.

You want both types of users to be able to work on all three classes, except that users with the Refund:Worker role may not delete Data-Refund-Gold data instances.

You can accomplish this with three rules:

Access Role

 
Access of

Data-Refund- Refund:Worker

Grant full access to all three classes.

Access of
Role to Object
Data-Refund- Refund:Super

Grant full access to all three classes.

Access
Deny
Data-Refund-Gold Refund:Worker

Deny Delete access to this class for workers; no change for others.

You can achieve the same results without any Access Deny rules, by granting needed Data-Refund-Gold access capabilities one-by-one. However, using one Access Deny rule in this situation is simpler and easier to understand and maintain.
