Inventions on Extending LDAP functionality- A TRIZ based Analysis
|
by Umakant Mishra
|
|
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, 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.
This article is a part of the main study made on LDAP based on 60 patents selected from US patent database. (For more details on the study please refer to the article “Inventions on LDAP- A study based on US Patents”, by Umakant Mishra, published in http://www.trizsite.com, July 2006.)

Inventions on Integrating LDAP with other directories- A TRIZ based analysis
|
by Umakant Mishra
|
|
Thus the LDAP architecture allows multiple LDAP servers work together on the same directory tree or multiple directory trees. Besides, LDAP being built on an open architecture, it is quite possible to integrate with other directory servers. LDAP can be mapped onto any other directory system so long as the X.500 data and service model as used in LDAP is not violated in LDAP interface.
LDAP server may store data in a Flat file, in RDBMS or in any other database. The LDAP client applications can use LDAP directory interface without having knowledge on the underlying data storage mechanism.
However, there are some issues and concerns in integrating multiple LDAP servers or Integrating LDAP directories with other directories. Different directories may use different schema for their directory objects. It is not possible to integrating database of one schema directly with database having another schema.
This article is a TRIZ based study of patents on integrating Lightweight Directory Access Protocol (LDAP) with other directories. The objective of this article is to find the major concerns in integrating LDAP with other directories, find the IFR and trends of evolution in LDAP integration and predict the future lines of inventions on integrating LDAP with other directories.
This article is a part of the main study made on LDAP based on 60 patents selected from US patent database. (For more details on the study please refer to the article “Inventions on LDAP- A study based on US Patents”, by Umakant Mishra, published in http://www.trizsite.com, July 2006.)

Inventions on using LDAP for different purposes-Part-1

by Umakant Mishra
|

This article is a part of the main study made on LDAP based on 60 patents selected from US patent database. (For more details on the study please refer to the article “Inventions on LDAP- A study based on US Patents”, by Umakant Mishra, published in http://www.trizsite.com, July 2006.)
Unlike other parts of the study which have tried to improve certain aspect of LDAP technology and application, this article includes the inventions that use LDAP for various different purposes.
This article is divided into 3 parts for convenience of size. The first part of the article includes 6 patents using LDAP for “e-commerce” and “Policy Management”. The second part includes 10 patents using LDAP for “Network Management” and “Telecommunications”. The third part of the article includes 11 patents using LDAP for “World Wide Web” and “Java and CORBA”. This is the first part of the article which analyses patents using LDAP for "e-commerce” and patents using LDAP for “Policy Management”.
The objective of this article is to know how is LDAP used for applications in e-commerce and Policy Management. The analysis of patents shows which Inventive Principles have been used to solve those inventions.

About TRIZsite Journal! |
|
The TRIZsite Journal publishes articles, case studies, personal
experience, class notes, training materials and other useful
papers on TRIZ and related topics.
This section is found to be very much appreciated by the readers.
We are getting suggestions to increase the number of articles. We are
expecting more articles to come from various authors soon. Our objective
is to include more and more articles in this section.

Call for papers and articles!
|
|
Articles are invited from writers on various fields to write on various
topics and issues. As the site is dedicated to TRIZ, we would prefer your
article should be relevant to TRIZ or TRIZ related concepts, such as,
traditional TRIZ, modified TRIZ, appliction of TRIZ, evolving
Techniques, your experience and case studies on TRIZ etc. However,
You can also write on similar related topics like, innovation,
creativity, intellectual property, other problem solving techniques,
comparision of TRIZ with other branches of study,
and so on as you can think.
Not only TRIZ professionals and practitioners, but everybody is welcome
including Students, Housewives, Artists, Philosophers to conribute
their papers to trizsite.com. We do not differentiate between a
senior person in a reputed company and just a novice thinker while
