Sun Java System Directory Server Enterprise Edition 6.3 Reference

Allowed Subtrees

An allowed subtree is specified by a minimum base DN. Clients are permitted to perform operations on entries at the minimum base DN or below the minimum base DN. By default, the minimum base DN is the root DN.

If a client requests a search operation that is targeted at a DN superior to the minimum base DN, Directory Proxy Server rewrites the DN to target the minimum base DN. If a client performs any other operation that is targeted at a DN superior to the minimum base DN, the operation is denied.
