Access Control in Directory Server

Directory Server offers an access control mechanism that works through aci attributes placed on directories entries. ACI stands for Access Control Instruction.

ACIs are evaluated based on a user's bind identity. ACIs can be evaluated therefore for all users who can bind to the directory. ACIs can also be applied for anonymous users who did not provide bind credentials. Rules about the bind identity can specify not only which users, but also which systems the users connect from, what time of day they connect, or what authentication method they use.

You configure an ACI to apply to the entries in its scope. Entries that can be in scope include entries on the branch of the directory information tree starting with the entry holding the ACI. Directory Server allows you to configure ACIs to be applied according to a number of different criteria. Directory Server also lets you configure ACIs not only to allow access, but also to deny access.

ACIs can specify which operations are allowed and denied. For example, you typically allow many users to read information, but only a few to update and add directory data.
