Controlling access to directory contents is an integral part of creating a secure directory. Access to data is managed with access control instructions (ACIs) that specify the access right to individual entries, all sub-entries below an entry, or all entries on a global basis.
Numerous or complicated ACIs require greater processing resources than a few simple ACIs. You can significantly reduce the performance of your directory by specifying a large number of ACIs or extremely complicated ACIs.
The directory server includes the ability to view the effective rights of a given user for a given entry. This feature simplifies the administration of the complex and powerful access control mechanism.
For an overview of the ACI model, see Access Control Principles in Sun OpenDS Standard Edition 2.0 Architectural Reference.
The following sections describe how to create ACIs to control access to data:
