Answer 1

To correct the error due to dependencies to install the python-ldap

download the wheel file

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

python 3.6 is suitable 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

Answer 2

From the Python LDAP documentation you can see that it requires a series of packages in order to get a proper installation (pre-build requisites). The commands you need to run, depends on the OS.

Sadly, this is intended for Linux based OS's.

I hope it helps! Cheers

Answer 3

For Windows what it worked for me in this case after tried many options was:

    python -m pip install --only-binary :all: ldap

Answer 4

It's because pip tries to compile OpenLDAP library and python-ldap is just a wrapper around binary lib. If you don't want to compile OpenLDAP library by yourself then I recommend this site: https://www.lfd.uci.edu/~gohlke/pythonlibs/

Download wheel-file you need, according to python version you use, for example python_ldap-3.2.0-cp37-cp37m-win_amd64.whl is for Python 3.6 64bit.

Then install:

python -m pip install python_ldap-3.2.0-cp37-cp37m-win_amd64.whl
