MongoDB Glossary - LDAP

In the world of databases, MongoDB is a popular choice for its flexibility, scalability, and ease of use. One of the many features that MongoDB offers is LDAP integration. In this article, we will explore what LDAP is and how it can be used with MongoDB.

What is LDAP?

LDAP stands for Lightweight Directory Access Protocol. It is an open and vendor-neutral protocol used for accessing and maintaining distributed directory information services over an IP network. LDAP is commonly used for centralized authentication and authorization services, making it an ideal choice for managing user accounts and access control in large organizations.

LDAP directories are hierarchical in nature, organized in a tree-like structure. Each entry in the directory represents an object, such as a user, group, or device, and is uniquely identified by a distinguished name (DN). The DN consists of a series of attributes that describe the object's location in the directory tree.

LDAP Integration with MongoDB

MongoDB provides built-in support for LDAP authentication, allowing you to leverage your existing LDAP infrastructure for user authentication and authorization. By integrating MongoDB with LDAP, you can centralize user management and simplify the authentication process.

When LDAP authentication is enabled, MongoDB acts as an LDAP client, connecting to the LDAP server to authenticate users. The LDAP server performs the authentication by verifying the user's credentials against the directory information stored in the LDAP directory.

LDAP integration with MongoDB offers several benefits:

  • Centralized User Management: With LDAP, you can manage user accounts in a centralized directory, eliminating the need to create and manage separate user accounts in MongoDB.
  • Single Sign-On (SSO): LDAP integration enables SSO, allowing users to authenticate once and access multiple systems and applications without the need to re-enter their credentials.
  • Enhanced Security: LDAP provides a secure and standardized method for user authentication, reducing the risk of unauthorized access to your MongoDB database.

Configuring LDAP Authentication in MongoDB

To enable LDAP authentication in MongoDB, you need to configure the LDAP settings in the MongoDB configuration file. The configuration includes specifying the LDAP server's address, port, and the base DN for user searches.

Once LDAP authentication is enabled, MongoDB will authenticate users against the LDAP server. If the authentication is successful, MongoDB will authorize the user based on the roles and privileges defined in the MongoDB database.

Here is an example of the LDAP configuration in MongoDB:

security:
  ldap:
    servers: ldap.example.com:389
    bind:
      method: simple
      username: "cn=admin,dc=example,dc=com"
      password: "password"
    userToDNMapping:
      "emailAddress": "mail"
    userSearch:
      baseDN: "ou=users,dc=example,dc=com"
      filter: "(uid={{username}})"

In this example, the LDAP server is located at ldap.example.com on port 389. The bind credentials are specified using a simple method with the admin username and password. The userToDNMapping maps the user's email address to the LDAP attribute "mail." The userSearch specifies the base DN and filter for searching user entries.

Summary

LDAP integration with MongoDB allows you to leverage your existing LDAP infrastructure for user authentication and authorization. By centralizing user management and simplifying the authentication process, LDAP integration enhances security and provides a seamless user experience.
