python-ldap: LDAP client API for Python

What is python-ldap?

python-ldap provides an object-oriented API to access LDAP directory servers from Python programs. Mainly it wraps the OpenLDAP client libs for that purpose.

Additionally the package contains modules for other LDAP-related stuff (e.g. processing LDIF, LDAPURLs, LDAPv3 sub-schema, etc.).

Not included: Direct BER support

See INSTALL for version compatibility

See TODO for planned features. Contributors welcome.

For module documentation, see:

Quick usage example:

import ldap
l = ldap.initialize("ldap://my_ldap_server.my_domain")
l.search_s("o=My Organisation, c=AU", ldap.SCOPE_SUBTREE, "objectclass=*")

See directory Demo/ of source distribution package for more example code.

The python-ldap project comes with a LICENCE file.

We are aware that its text is unclear, but it cannot be changed: all authors of python-ldap would need to approve the licence change, but a complete list of all the authors is not available. (Note that the Git repository of the project is incomplete. Furthermore, commits imported from CVS lack authorship information; users "stroeder" or "leonard" are commiters (reviewers), but sometimes not authors of the committed code.)

The current maintainers assume that the license is the sentence that refers to "Python-style license" and assume this means a highly permissive open source license that only requires preservation of the text of the LICENCE file (including the disclaimer paragraph).

All contributions committed since July 1st, 2021, as well as some past contributions, are licensed under the MIT license. The MIT licence and more details are listed in the file LICENCE.MIT.
