Content Synchronization Operation
Status of This Memo
This memo defines an Experimental Protocol for the Internet
community. It does not specify an Internet standard of any kind.
Discussion and suggestions for improvement are requested.

IESG Note
The IESG notes that this work was originally discussed in the LDUP
working group. The group came to consensus on a different approach,
documented in RFC 3928; that document is on the standards track and
should be reviewed by those considering implementation of this
proposal.
Abstract
This specification describes the Lightweight Directory Access
Protocol (LDAP) Content Synchronization Operation. The operation
allows a client to maintain a copy of a fragment of the Directory
Information Tree (DIT). It supports both polling for changes and
listening for changes. The operation is defined as an extension of
the LDAP Search Operation.

RFC 4533 LDAP Content Synchronization Operation June 2006
1. Introduction
The Lightweight Directory Access Protocol (LDAP) [RFC4510] provides a
mechanism, the search operation [RFC4511], that allows a client to
request directory content matching a complex set of assertions and to
