![]() It was also the first entirely open-source suite of client and server applications derived from LDAPv3.3.Īmongst other factors, OpenLDAP also enjoyed popularity because it enabled IT admins to modify it to fit their organizations’ needs better. This version included advanced security features, updated platform support, and bug fixes. This remains the latest and most prevalent version of LDAP today.įollowing this milestone, Kurt Zeilenga started the OpenLDAP Project by releasing OpenLDAP 1.0 in 1998. ![]() LDAP version 3 was proposed and accepted as the internet standard for directory services in the late nineties. Due to these efficiencies, LDAP found great success and became the de facto Internet directory services authentication protocol in no time. LDAP solved these problems by allowing for authentication and authorization of users to IT resources while reducing overhead, bandwidth use, and demand on endpoints. Little wonder that most computers on people’s desks in the early 1990s couldn’t connect to an X.500 directory service.Ĭonsequently, in those days, X.500’s usage was limited to specific systems like mainframes, mini-computers, or micro-computers, and generally not PCs. X.500 had a large bandwidth-intensive footprint, making it strenuous for both the systems and the network. It was created to be a lightweight, low-overhead version of the X.500 directory services protocols used at the time, such as directory access protocol (DAP). LDAP was developed in 1993 by Tim Howes and his colleagues at the University of Michigan. In a nutshell, LDAP enables the secure management of users and IT resources in a directory, making it possible to control access to different parts of a computer network. Although directory services may use additional protocols like Kerberos, SAML, RADIUS, SMB, Oauth et.c., most still use LDAP today. ![]() LDAP is one of the core protocols used for these services. To understand what LDAP is, it’s best to understand what it was used for in the first place: directory services.ĭirectory services securely manage users and their access rights to IT resources within an organization using certain protocols. We’ll also take a dive into explaining how it works, how it’s used, how to get started, and which LDAP server solutions might be right for your needs. This post covers everything you need to know about LDAP, from its origins to its place in the contemporary cloud-driven world. In that time, the protocol has expanded and evolved to meet changing IT environments and business needs. Extending LDAP to a Full Cloud Directoryįor nearly 3 decades, organizations have been using the LDAP (Lightweight Directory Access Protocol) for user management, attributes, and authentication.
