I can't install python-ldap

Question

When I run the following command:

sudo pip install python-ldap

I get this error:

In file included from Modules/LDAPObject.c:9:

Modules/errors.h:8: fatal error: lber.h: No such file or directory

How can I fix this?

The python-ldap is based on OpenLDAP, so you need to have the development files (headers) in order to compile the Python module. If you're on Ubuntu, the package is called libldap2-dev.

Debian/Ubuntu:

sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev

RedHat/CentOS:

sudo yum install python-devel openldap-devel

Thanks for that. It's got further it's now failing with sasl.h no such file or directory – VacuumTube Jan 22 '11 at 14:57

@VacuumTube: Missing headers are almost always a sign for missing `-dev` packages (sometimes also named `-devel`). Just do `apt-cache search sasl | grep dev` and you'll probably find the right package - I would guess it's `libsasl2-dev`. – AndiDog Jan 22 '11 at 15:02

You don't have to compile from source on Windows. Just use one of the installers from https://pypi.python.org/pypi/python-ldap/. – Semmel Sep 19 '13 at 02:14

Also, Windows users can extract the .msi installer @Semmel mentioned to install into a virtualenv: [How to install python-ldap on a python 2.7 virtualenv on windows without compiling](http://stackoverflow.com/questions/15918188/how-to-install-python-ldap-on-a-python-2-7-virtualenv-on-windows-without-compili) (see update 2) – Dave Oct 29 '13 at 17:11
On Windows you can also use Chris Gohlke's excellent resource for Windows installers: http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap – Josh Hemann Feb 27 '14 at 17:18
Thanks @AndiDog. the issue was resolved as soon as I installed the `-dev` library :) – Babak K Aug 04 '15 at 20:27

Full list should be sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev – James Nov 10 '15 at 02:35
Notice that you need to run 'sudo apt-get update' first. – Slark Apr 10 '17 at 11:28
Well this is odd. I have installed `libldap2-dev` but the headers haven't been installed. Everything else in the package (libs, man pages) has. Edit: --reinstall and it's fine. – OrangeDog Mar 23 '18 at 17:39
@TrinhHoangNhu: Why this that the full list? Can you explain how you found those dependencies? – Lii Apr 27 '18 at 09:05

Use `python3-dev` instead of `python-dev` if you are using Python 3. – phoenix Aug 09 '19 at 11:43
Sometimes also known as `python36-devel` or `python3-devel.x86_64` or `python36-devel.x86_64` (aws). When in doubt: `yum search python | grep -i dev` – Amit Naidu Aug 25 '20 at 23:56

Worth noting in 2022 on Debian 11, I only needed to install `libldap2-dev` and `libsasl2-dev`. (Already had `python3-virtualenv`.) – Seth Falco Jul 16 '22 at 06:57
for me it didn't find `python-dev` so I did this: `sudo apt-get install libsasl2-dev python-dev-is-python3 libldap2-dev libssl-dev` – Karina Klinkevičiūtė Jan 06 '23 at 20:23

On CentOS/RHEL 6, you need to install:

sudo yum install python-devel
sudo yum install openldap-devel

and yum will also install cyrus-sasl-devel as a dependency. Then you can run:

pip-2.7 install python-ldap

"Don't blindly remove/install software"

In a Ubuntu or Debian based distro, you can use apt-file to find the name of the exact package that includes the missing header file.

# do this once
sudo apt-get install apt-file
sudo apt-file update

$ apt-file search lber.h
libldap2-dev: /usr/include/lber.h

As you could see from the output of apt-file search lber.h, you'd just need to install the package libldap2-dev.

sudo apt-get install libldap2-dev

Windows: I completely agree with the accepted answer, but digging through the comments took a while to get to the meat of what I needed. I ran across this specific problem with Reviewboard on Windows using the Bitnami. To give an answer for windows then, I used this link mentioned in the comments:

http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap
placed that wheel (whl file) into my reviewboard install directory

Then, executed the following commands

easy_install pip
pip install python_ldap-2.4.20-cp27-none_win32.whl

(because I had python 2.7 and a 32bit install at that)

easy_install python-ldap

For those having the same issue of missing Iber.h on Alpine Linux, in a docker image that you are trying to adapt to Alpine for instance.

The package you are looking for is: openldap-dev

So run

apk add openldap-dev

Available from version 3.3 up to Edge

Available for both armhf and x86_64 Architectures.

I had problems with the installation on Windows, so one of the solutions is to install the ldap package manually.

A few steps:

Go to the page pyldap or/and python-ldap and download the latest version *whl.
Open a console then cd to where you've downloaded your file like some-package.whl and use:

pip install some-package.whl

The current version for pyldap is 2.4.45. On a concrete example the installation would be:

pip install .\pyldap-2.4.45-cp37-cp37m-win_amd64.whl

# or
pip install .\python_ldap‑3.3.1‑cp39‑cp39‑win_amd64.whl

Output:

Installing collected packages: pyldap
Successfully installed pyldap-2.4.45

EDIT

You can install the proper version for Python-3.X though using following command:

# if pip3 is the default pip alias for python-3
pip3 install python3-ldap

# otherwise 
pip install python3-ldap

Also here is the link of PiPy package for further information: python3-ldap 0.9.8.4

OR

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: https://github.com/cannatag/ldap3

pip install ldap3

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)

For most systems, the build requirements are now mentioned in python-ldap's documentation, in the "Installing" section.

If anything is missing for your system (or your system is missing entirely), please let maintainer know! (As of 2018, I am the maintainer, so a comment here should be enough. Or you can send a pull request or mail.)

As of December 2021 there was/is a strange problem with the ldap library (at least in Arch Linux/Manjaro).

While installing python-ldap (at 'Building wheel for python-ldap'), I got the message 'ERROR: Failed building wheel for python-ldap':

  /usr/bin/ld: cannot find -lldap_r
  collect2: error: ld returned 1 exit status
  error: command '/usr/bin/gcc' failed with exit code 1

A workaround is provided at Support for OpenLDAP 2.5+ #432.

I cite:

As a workaround create the file /usr/lib64/libldap_r.so with content INPUT ( libldap.so ). The approach works on all systems that use a GNU ld-compatible linker.
# cat > /usr/lib64/libldap_r.so << EOF
INPUT ( libldap.so )

As a general solution to install Python packages with binary dependencies [1] on Debian/Ubuntu:

sudo apt-get build-dep python-ldap
# installs system dependencies (but not the package itself)
pew workon my_virtualenv # enter your virtualenv
pip install python-ldap

You'll have to check the name of your Python package on Ubuntu versus PyPI. In this case they're the same.

Obviously doesn't work if the Python package is not in the Ubuntu repos.

[1] I learnt this trick when trying to pip install matplotlib on Ubuntu.
