Tim Howes and his other friends were working on X.500 to introduce the campus to Unix and the internet. X.500 was the International Organization for Standardization’s standard for directory services. After working on this project, he soon realized that this protocol is too hefty and complex for desktop machines.
LDAP is an acronym for Lightweight Directory Access Protocol.Tim Howes invented the LDAP while pursuing his graduation from the University of Michigan. The necessity of a light protocol for the desktops initiated the LDAP search.
LDAP was first introduced in 1993 with the purpose to acclimate computer systems with something easy. It has been proven highly successful since the very beginning.
The Internet standard declared LDAP.v3 as directory services in 1997. Even the modeling of the Open LDAP is also galvanized by the foundation of LDAP. LDAP has become the core aspect of many modern cloud directories. In the late 1990s, open source solutions like Open Directory, influenced by LDAP, formed the foundation for Microsoft Active Directory as well.
It is mainly used as an authentication protocol for all directory services. In the past, LDAP was used as a database for information like users’ information, credentials, group associations, and attributes about users.
Enactment of LDAP
The time needed to implement and customize LDAP-influenced infrastructure to fulfill the identity management of a modern organization can be compelling. LDAP authentication has authorized potential. In the past, LDAP has been an on-prem implementation that demands dedicated servers that combine an organization’s entire identity management infrastructure.
It is quite challenging for smaller and cloud-forward IT organizations to achieve this kind of setup. Most modern organizations prefer to transfer their complete on-prem identify management infrastructure to the cloud.
Common Challenges of LDAP
The LDAP authentication simply goes after the server model. The client already possesses an LDAP-ready system. An application that requests information from a joined LDAP database and the server. The LDAP database has all the stored credentials.
The LDAP server authenticates the credentials given by the user against their core identity. The LDAP database has a smooth framework that stores username and password information. Apart from this, it also stores other sorts of different attributes like groups associated with them, telephone number, address, and many other things.
Working Procedure of LDAP authentication among a Client and Server
LDAP authentication has a very simple and two steps working procedure between the client and a server. Check out the following steps to know about them.
- A client sends a request from its end for the information which is stored within an LDAP database. The user’s credentials to an LDAP server are also included in it.
- If the client’s credentials match with the core user identity, the client will automatically get access.
- After granting access, all the requested information like attributes, group memberships, or other data will be received by the client.
- In case, if the client’s credentials don’t match, the access will be denied.
It can be concluded that LDAP authentication will be the basic primary element of identity management in the future too.
