In today’s digital landscape, streamlining user access while maintaining security is crucial. Configuring LDAP single sign-on (SSO) for Burp Suite Enterprise Edition (EE) allows teams to leverage existing organizational credentials, enhancing both convenience and security. This guide walks you through the process, ensuring a smooth integration of LDAP with Burp Suite EE.

Understanding the Components

Before diving into configuration, it’s essential to understand the components involved:

  • LDAP (Lightweight Directory Access Protocol): A protocol for accessing and maintaining distributed directory information, commonly used for authentication.
  • Burp Suite EE: A robust tool for managing web application security testing within teams, offering features like centralized management and scalability.
  • SSO (Single Sign-On): Enables users to log in once and access multiple applications without re-entering credentials, improving user experience and security.

Gathering Necessary Information

To configure LDAP, you’ll need:

  • LDAP Server URL: The server’s address, e.g., ldap://example.com:389 or ldaps://example.com:636.
  • Base DN: The starting point for searching user accounts, e.g., dc=example,dc=com.
  • User Search Filter: Specifies how users are located, e.g., (uid={username}).
  • Bind Credentials (if required): The account used by Burp to connect to the LDAP server.

Accessing the Burp Suite EE Admin Interface

  1. Log in to the Admin Interface: Access Burp Suite EE via a web browser using the URL https://<server>:<port>/burp, replacing <server> and <port> with your server’s details.
  2. Navigate to Authentication Settings: Locate the “Authentication” or “User Management” section in the admin interface.

Configuring LDAP Settings

  1. Enter LDAP Server Details:

    • Server URL: Enter the LDAP server’s URL.
    • Base DN: Specify the base DN for user searches.
    • User Search Filter: Use a filter like (uid={username}) to locate user accounts.

  2. Bind Credentials (if required): Provide the bind DN and password if the LDAP server requires authentication.

  3. Test the Configuration: Use Burp’s test connection feature to ensure the setup works. Troubleshoot common issues like incorrect URLs, ports, or typos if the test fails.

Enabling LDAP Authentication

After successful testing, enable the LDAP authentication method in Burp. Users can now log in using their LDAP credentials.

Enhancing Security

  • Use LDAPS: Encrypt communication by using LDAPS to prevent plaintext transmission of sensitive information.
  • Principle of Least Privilege: Ensure the bind account has minimal necessary privileges.

User Management Considerations

  • User Provisioning: Automatically add new users to Burp upon their first LDAP login.
  • Account Lockouts and Resets: Integrate with existing systems for handling account issues.

Testing and Monitoring

  • Thorough Testing: Test successful and failed login attempts, including scenarios where the LDAP server is unavailable.
  • Logging and Monitoring: Track login attempts and server health to identify issues early.

Conclusion

Configuring LDAP SSO for Burp Suite EE enhances user experience and security by streamlining access with existing credentials. By following these steps, organizations can efficiently manage user access, improving both productivity and security.
