ldaptor
A Pure-Python Twisted library for LDAP
Decision gist · record as of 2026-08-14
Yes, if you are building on Twisted or need async LDAP operations. The library is stable (Production/Stable status), has no known vulnerabilities, and low install friction. The gap between the latest release (2021-02-28) and active repo commits (2026-05-25) suggests development may outpace PyPI releases; verify current Python version support before adopting in new projects. Suitable for established LDAP integration tasks.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Twisted reactor event loop; LDAP operations are async/deferred-based, not blocking calls.
- Low install friction; ships as a wheel.
- Maintenance is active with recent commits (2026-05-25), though the latest PyPI release is from 2021-02-28.

What it is and what it does
Ldaptor is a pure-Python LDAP client library that runs on top of Twisted, providing asynchronous access to LDAP directory services. It handles the full LDAP protocol stack—client connections, authentication, directory searches, and filter parsing—without requiring compiled C extensions. The library also includes utilities for LDIF format generation, Samba password operations, and command-line tools.
You use it when you need to query or authenticate against LDAP directories from Python, particularly in applications already built on Twisted or where async I/O is desired. It parses LDAP filters from text, generates protocol messages, and manages the connection lifecycle through Twisted's deferred-based concurrency model. Dependencies are all pure-Python (Twisted, pyparsing, passlib, six, zope.interface), so installation is straightforward.
Use it for
- Authenticate users against an LDAP directory in a Twisted-based web or network service.
- Query LDAP directory entries (users, groups, organizational units) and export results as LDIF.
- Implement Samba password changes programmatically from a Python application.
- Build LDAP client tools or utilities that need to parse and generate LDAP protocol messages.
- Integrate directory lookups into async Python applications without blocking the event loop.

Install
ldaptor on PyPI
Before you install
Low install friction; ships as a wheel. Maintenance is active with recent commits (2026-05-25), though the latest PyPI release is from 2021-02-28. Depends on Twisted and four other pure-Python libraries, all widely available.
Requires Twisted reactor event loop; LDAP operations are async/deferred-based, not blocking calls.
