ldap3 2.10.2rc4

A pure Python LDAPv3 client library strictly conforming to RFC 4510

ldap3 is a strictly RFC 4510 conforming LDAP V3 pure Python client library. The same codebase runs in Python 2, Python 3, PyPy and PyPy3.

A more pythonic LDAP

LDAP operations look clumsy and hard-to-use because they reflect the old-age idea that time-consuming operations should be performed client-side to not hog the server with heavy elaborations. To alleviate this ldap3 includes a fully functional Abstraction Layer that lets you interact with the LDAP server in a modern and pythonic way. With the Abstraction Layer you don’t need to directly issue any LDAP operation at all.

Thread safe strategies

In multithreaded programs you must use one of SAFE_SYNC (synchronous connection strategy), SAFE_RESTARTABLE (restartable syncronous connection strategy) or ASYNC (asynchronous connection strategy).

Each LDAP operation with SAFE_SYNC or SAFE_RESTARTABLE strategies returns a tuple of four elements: status, result, response and request:

• status: states if the operation was successful

• result: the LDAP result of the operation

• response: the response of a LDAP Search Operation

• request: the original request of the operation

The SafeSync strategy can be used with the Abstract Layer, but the Abstract Layer currently is NOT thread safe. For example, to use SAFE_SYNC:

from ldap3 import Server, Connection, SAFE_SYNC
server = Server('my_server')
conn = Connection(server, 'my_user', 'my_password', client_strategy=SAFE_SYNC, auto_bind=True)
status, result, response, _ = conn.search('o=test', '(objectclass=*)')  # usually you don't need the original request (4th element of the returned tuple)

With ASYNC you must request the response with the get_response() method.
