Question 1

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

Any ideas how to fix this?

Question 2

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

Question 3

To install python-ldap successfully with pip, following development libraries are needed (package names taken from ubuntu environment):

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

Question 4

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

Question 5

In Ubuntu it looks like this :

 $ sudo apt-get install python-dev libldap2-dev libsasl2-dev libssl-dev
 $ sudo pip install python-ldap

Question 6

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

Question 7

“Don’t blindly remove/install software”

In a Ubuntu/Debian based distro, you could 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

Question 8

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.

Question 9

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

zypper install openldap2-devel cyrus-sasl-devel python-devel libopenssl-devel

Question 10

On Fedora 22, you need to do this instead:

sudo dnf install python-devel
sudo dnf install openldap-devel

Question 11

On OSX, you need the xcode CLI tools. Just open a terminal and run:

xcode-select --install

Question 12

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.)

Question 13

python3 does not support python-ldap. Rather to install ldap3.

Question 14

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

download the whl file

http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap.

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

Question 15

In FreeBSD 11:

pkg install openldap-client # for lber.h
pkg install cyrus-sasl # if you need sasl.h
pip install python-ldap

Question 16

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.

Question 17

For alpine docker

apk add openldap-dev

if the python version is 3 and above try

pip install python3-ldap

Question 18

If you’re working with windows machines, you can find ‘python-ldap’ wheel in this Link and then you can install it

Question 19

for those who are using alphine linux, apk add openldap-dev

Question 20

sudo apt-get install build-essential python3-dev python2.7-dev libldap2-dev libsasl2-dev slapd ldap-utils python-tox lcov valgrind
