I was able to resolve this issue by the foll. workaround :

$ yum install -y yum-utils
$ yum-builddep -y python-ldap
$ pip install -U python-ldap

Actually, it's not a work around, it's the proper way to do it if you are installing the dependencies through pip (python-ldap and python-yaml are bindings to C libraries, these needs to be compiled, so you need the headers and a compiler).

I need to specify if in the documentation.

Also, the ldapcherry dependency are already packaged by CentOS (with Epel) and Debian/Ubuntu, I should probably mention it and document it, it will be less fragile than pip.

[smacz42]

If you're installing on CentOS and already have pip, then the following should work:

$ sudo yum install python-devel gcc openldap-devel

But it seems that you want three things in the documentation:

1. Install ldapcherry through pip
2. Install dependencies through OS package management and install ldapcherry with pip
3. Install dependencies through OS package management and run setup.py

Would you like this before "From the sources" in install.rst?

Yes please - thanks. :)-
