I can't install python-ldap

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?

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 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

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)

To correct the error due to dependencies to install the python-ldap: Windows 7 and Windows 10

Download the whl file from:

https://github.com/cgohlke/python-ldap-build (old link http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap no longer working as reported here)

Python 3.6 suit with

python_ldap-3.2.0-cp36-cp36m-win_amd64.whl

Deploy the file in:

C:\python36\Scripts\

Install it with:

python -m pip install python_ldap-3.2.0-cp36-cp36m-win_amd64.whl

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-is-python3 libldap2-dev libssl-dev

Red Hat/CentOS:

sudo yum install python-devel openldap-devel

Also adding libzbar-dev during the installation of python-ldap when building Docker solved it for me.

The full command becomes:

apt-get install -y python-dev libldap2-dev libsasl2-dev libssl-dev libzbar-dev

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, it doesn't work if the Python package is not in the Ubuntu repositories.

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

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:

Archived: Unofficial Windows Binaries for Python Extension Packages, 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 32-bit install at that)

easy_install python-ldap

"Don't blindly remove/install software"

In a Ubuntu or Debian-based distribution, 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

Output:

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

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.

On openSUSE you need to install the packages openldap2-devel, cyrus-sasl-devel, python-devel and libopenssl-devel.

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

The package python-dev is deprecated or not longer available. You can use this instead:

sudo apt-get install libsasl2-dev python2-dev python2 python-dev-is-python3 libldap2-dev libssl-dev
pip install python-ldap

A hack answer for FreeBSD 13.1 (yes, I know this is deep South of best practices, but I just needed a quick fix):

pkg install openldap24-client

cd /usr/local/include/python3.9
ln -s ../<all of the below> .

lber.h
lber_types.h
ldap.h
ldap_cdefs.h
ldap_features.h
ldap_schema.h
ldap_utf8.h
openldap.h
sasl

pip install python-ldap

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 )
EOF

You need to install libldap2-dev (sudo apt-get install libldap2-dev), but python-dev is also important. Remember to use the version you have (sudo apt-get install python3.8-dev or sudo apt-get install pythonX.X-dev)

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.)
