Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Static groups in LDAP directories are prone to errors and maintenance challenges due to manual updates and potential inaccuracies, especially when membership changes frequently, leading to inefficiencies in group management.

Innovation Solution

Implementing a group management module that dynamically adds and removes entries from groups based on attribute values, allowing for automatic membership updates and creation of new groups as needed, thereby eliminating the need for manual maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If static groups are used with manual updates, then group membership can be controlled, but errors and maintenance challenges increase

Engineering Contradiction:

Improvegroup membership accuracyVSAvoidmaintenance burden

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent transforms static groups into dynamic groups that automatically update membership based on attribute values. The group membership is no longer manually maintained but dynamically adjusted through LDAP queries that monitor attribute changes, resolving the contradiction between reliability and ease of operation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system enables self-service by allowing groups to automatically manage their own membership through attribute-based rules. When entry attributes change, the LDAP server automatically adds or removes members from groups without human intervention, eliminating manual maintenance while ensuring accuracy.

Inventive Principle:

Principle #25Self-service

2Productivity

If manual updates are used for group membership, then control is maintained, but efficiency decreases

Engineering Contradiction:

Improvegroup management efficiencyVSAvoidtime for manual updates

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent implements continuous automatic monitoring of LDAP entry attributes through dynamic group membership. The system continuously queries for attribute changes and automatically updates group memberships, eliminating interruptions and manual batch updates, thereby improving productivity and reducing time loss.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system establishes feedback loops where LDAP attribute changes trigger automatic group membership updates. The dynamic groups continuously monitor entry attributes and provide real-time feedback by automatically adjusting membership, eliminating manual intervention and significantly improving management efficiency.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If static groups are used, then simplicity is maintained, but adaptability to changing membership requirements decreases

Engineering Contradiction:

Improveresponse to membership changesVSAvoidgroup management system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses parameter changes in LDAP entry attributes to dynamically control group membership. When attributes such as department, role, or status change, the system automatically detects these parameter changes and adjusts group membership accordingly, providing high adaptability while maintaining manageable complexity through standard LDAP mechanisms.

Inventive Principle:

Principle #35Parameter changes

AI summary

A method and apparatus for managing a directory server is described. In one embodiment, a value of an attribute of an entry in the directory server is received. The value of the attribute identifies a group. The entry is added to a group based on the value of the attribute. A content of the group is dynamically changed based on the value of the attribute of the entry.
