AI Technical Summary

Problems solved by technology

The disadvantage is that it slows down the processing of operations to a significant extent
An additional disadvantage with current solutions is that it becomes increasingly difficult to manage distributed directories, leading to incorrect evaluation of directory queries due to topology information at brokers

[0031] overview

[0032] image 3 A proxy directory system 40 is shown. System 40 first includes a proxy directory server 42 . The proxy directory server 42 is connected to the client server 44 and receives a directory request (client request) from the client server 44 . Proxy directory server 42 is also connected to a plurality of directory servers 46, 48, 50 identified as host 1, host 2, and host 3, respectively. The proxy directory server 42 routes client requests to the appropriate directory server 46 , 48 , 50 . Proxy directory server 42 also includes processor 62 and data storage 64, the functions of which will be described below.

[0033] Discover directory topology

[0034] Proxy Directory Server 42 requires the following topology information to be able to route client requests:

[0035] (i) Naming context to server mapping

[0036] (ii) Determine which servers master the replicated context.

[0037] Proxy directory server 42 performs the followi...

Abstract

A proxy directory server discovers the topology of distributed directory server immediately after starting up and before accepting client requests. Immediately after starting up, the proxy server executes queries to extract the structured data corresponding to directory distribution information from the distributed directory servers. Dynamic topology reconfiguration of the distributed directory is achieved by any dynamic configuration changes made to the topology informat ion directly at the proxy during operation being propagated by means of directory update operations to the distributed directory servers.

Description

technical field [0001] The present invention relates to a method, a proxy server and a proxy directory system for distributed directories using proxies. Background technique [0002] introduction [0003] Directories are specialized databases optimized for read access that have the ability to store information about heterogeneous real-world entities (such as people, resources, policies, services, applications, etc.) in a single instance, making them a secure and a key component of an identity management framework. Typically, a directory consists of a directory information tree (DIT) of entries. For example, the standard way to access directories on the Internet is LDAP (Lightweight Directory Access Protocol (v3): Technical Specification, RFC 3377. http: / / www.ietf.org / rfc / rfc3377.txt), which allows Distribute the DIT on multiple servers. LDAP supports distributed processing of directory operations using a referral mechanism. Each server contains a subtree of entries call...
