How to Add a New Entry to LDAP Server with Golang

Adding entries to an LDAP (Lightweight Directory Access Protocol) server can be a bit daunting, especially when encountering errors. One common error developers face is the LDAP Result Code 65 "Object Class Violation", which indicates that there’s a problem with the structural object class in the entry you’re trying to add. In this guide, we’ll explore how to troubleshoot this issue and provide a clear path to successfully adding new entries to your LDAP server using Golang.

Understanding the Problem

When you receive the Object Class Violation error, it typically means that you haven’t specified the necessary object class or that your entry lacks mandatory attributes. Each LDAP object type is defined by its object class, which outlines the required and optional attributes for that object.

Common Causes of Object Class Violation

Missing Object Class: Each LDAP entry must have at least one structural object class defined.

Omitted Mandatory Attributes: Various object classes have specific attributes that must be included when creating an entry.

The Solution: Adding Entries Correctly

Let's walk through the proper steps to add a new entry to your LDAP server using Golang effectively.

Step 1: Establish a Connection

Before adding entries, you need to connect to the LDAP server:

Step 2: Bind to the LDAP Server

You need to authenticate with valid credentials (username and password). Make sure the user has permission to add entries.

Step 3: Create an Add Request

When creating an add request, ensure you specify the correct object classes and mandatory attributes. For example, if you want to add a group entry, the objectClass should be properly defined:

Step 4: Execute the Add Request

Now you can attempt to add the entry to the server with the Add function.

Reviewing Your Object Classes

If you're still encountering issues, it’s a good practice to review the LDAP server’s schema to identify the correct object classes and mandatory attributes. You can query the schema as follows:

This command will return a schema listing showing object classes. For example, an object class definition for person is:

From this output, make note of:

Mandatory attributes: Must include cn and sn if using person class.

Optional attributes: Include attributes like description which can enhance the entry but are not required.

Conclusion

Understanding how to add entries to an LDAP server with Golang requires a clear grasp of LDAP schemas and object classes. By following the steps outlined in this post, you should be able to avoid the common pitfalls that lead to the Object Class Violation error. Remember to consult the server’s schema to ensure that your entries adhere to the correct formats and requirements.

Whether you’re managing user directories or application configurations, mastering LDAP manipulation will greatly enhance your Golang capabilities. Happy coding!
