Question

I am trying to get ldap authentication to work on Plone version 4.2. I have hammered at the issue for several hours without results. I have even tried these steps:

1. Install python-ldap 2.6 (C:\Python26)
2. Install Plone 4.2 with the installer (D:\Plone)
3. Edit buildout.cfg with plone.app.ldap in the EGG and ZCML section
4. Create a new folder called python_ldap-2.3.12-py2.6.egg in D:\Plone\buildout-cache\eggs\
5. Copy C:\Python26\lib\site-packages\python_ldap-2.3.12-py2.6.egg-info to D:\Plone\buildout-cache\eggs\python_ldap-2.3.12-py2.6.egg\ and rename to EGG-INFO
6. Also copy the ldap folder in C:\Python26\lib\site-packages\ to D:\Plone\buildout-cache\eggs\python_ldap-2.3.12-py2.6.egg\
7. Also copy the file ldapurl.py to C:\Python26\lib\site-packages\ to D:\Plone\buildout-cache\eggs\python_ldap-2.3.12-py2.6.egg\
8. Next copy:
   folder: C:\Python26\lib\site-packages\python_ldap-2.3.12-py2.6.egg-info
   folder: C:\Python26\lib\site-packages\ldap
   to D:\Plone\python\Lib\site-packages
9. Start commandbox and run bin\buildout
10. Start Plone, log in as admin and go to the extra products section. Here you will find the LDAP product. Install it and enter you LDAP details.

None of that really helped. When i try bin/buildout, I get the following message:

What am i doing wrong? Help wil be deeply appreciated

Answer 1

Your buildout ran successfully, there were no problems there. Some of the packages you picked were not pinned, so your buildout reported what versions it choose for you.

Your server itself is not indeed running because the Python LDAP egg you installed seems to be incorrectly installed. The buildout-cache/eggs/python_ldap-2.3.12-py2.6.egg/ldap/_ldap.so library file is missing.

Remove the whole egg (rm -rf buildout-cache-eggs/python_ldap-2.3.12-py2.6.egg) make sure you have the OpenLDAP 2.x library and headers installed on your system (on Ubuntu and Debian the libldap2-dev should be enough). Then re-run buildout to reinstall the egg.

Alternatively, you could try and install the system python-ldap package (remove the egg) and see if buildout picks that up instead.
