LDAP application authentication

An LDAP application authentication diagram shows how an application uses a directory server to find users and groups. The employee portal is an LDAP client: it binds to OpenLDAP over LDAPS on port 636, then searches the relevant People and Groups containers. This structure helps an administrator see where identity data lives and which connection needs to be secured. It also creates a clear place to document the search bases and the applications that depend on them. Do not include bind passwords or secrets in a shared diagram. In a production environment, add the actual hosts, certificate requirements and least-privilege service account only where the audience is authorized to see them.

CASE ANALYSIS

Scenario

LDAP application integration

Key decisions

Client: Identify the application that binds.
Transport: Label encrypted LDAPS and its port.
Directory: Identify the server receiving searches.
Search bases: Show the user and group containers.

When to reuse this

Use this to explain a basic application-to-directory integration; keep credentials and other secrets out of the diagram.

FAQ

Frequently asked questions

What does an LDAP bind do?01

A bind establishes an LDAP session, often using a service account or user credentials, before the client performs permitted directory operations.

Why label LDAPS 636?02

It distinguishes an encrypted LDAP connection from unencrypted LDAP and documents the port used by the application.

What are search bases?03

Search bases are distinguished names that limit where an LDAP client looks for users, groups or other entries.
