Abstract:
The LDAP server stores the directory information in a
database. The client makes a TCP/IP connection and sends requests to an LDAP
server. The LDAP server executes the client requests and returns a response to
the client. LDAP offers nine basic functional operations, viz., add, delete,
modify, bind, unbind, search, compare, and modify distinguished name and
abandon.
Apart from the above basic operations, LDAP v3 includes new
mechanism called Extended Operations, which allows additional operations to be
defined for services not available in this protocol, for instance digitally
signed operations and results. Using this feature it is possible to provide new
operations and extend the functionality of existing operations.
The extended operation allows clients to make requests and
receive responses with predefined syntaxes and semantics. These may be defined
in RFCs or be private to particular implementations. Each request must have a
unique object identifier assigned to it (RFC 2251,
www.ietf.org/rfc/rfc2251.txt). The server will respond to this with a message
called ExtendedResponse. If the server does not recognize the request name, it
will return an error.
This article analyzes patents on Lightweight Directory
Access Protocol (LDAP) Extended Functionality. The objective of this article is
to find out what are the major concerns in LDAP Extended functionality, what
inventions have already been made and which areas are lying unexplored.
