LDAP

Open Source Lightweight Directory Access Protocol Solutions

LDAP (Lightweight Directory Access Protocol) is an application protocol for accessing directory services. It runs on a layer above the TCP/IP stack incorporating simplified encoding methods, and offers a convenient way to connect to, search, and modify Internet directories, specifically X.500-based directory services. It is an open, vendor-neutral, industry standard application protocol. LDAP utilizes a client-server model.

This protocol is specifically targeted at management applications and browser applications that provide read/write interactive access to directories.

The main benefit of using an LDAP server is that information for an entire organization can be consolidated into a central repository. LDAP supports Secure Sockets Layer (SSL) and Transport Layer Security (TLS), so that sensitive data can be protected. LDAP servers are used for a variety of tasks including, but not limited to, user authentication, machine authentication, user/system groups, asset tracking, organization representation, and application configuration stores.
