erreur installation ldap et plone 4

Bonjour,

Je me suis lancer pour un mémoire de fin d'année dans la mise en place d'un intranet basé sur plone 4 et je souhaite installer le module LDAP pour une authentification Active Directory.

Voici la procédure que j'ai faite :

J'ai éditer le fichier base.cfg :

Dans la section instance j'ai inclut à eggs :

Code:

${python-ldap:egg}

ensuite dans le fichier buildout.cfg :

eggs :

j'ai rajouter :

Code:

1
2
3
4
5
6
Products.PloneLDAP
plone.app.ldap
Products.LDAPMultiPlugins 
Products.LDAPUserFolder 
dataflake.cache 
dataflake.ldapconnection

dans la partie parts :

Code:

1
2
3
 
openldap
python-ldap

j'ai ensuite créer deux sections :

Code:

1
2
3
4
5
6
7
8
9
10
 
[openldap] recipe = zc.recipe.cmmi url = <a href="ftp://ftp.openldap.org/pub/OpenLDAP/openldap-stable/openldap-stable-20100219.tgz" target="_blank">ftp://ftp.openldap.org/pub/OpenLDAP/...e-20100219.tgz</a> extra_options = --with-sasl --with-tls --enable-slapd=no
 
[python-ldap]
recipe = zc.recipe.egg:custom 
egg = python-ldap 
include-dirs =
    ${openldap:location}/include 
library-dirs =
    ${openldap:location}/lib

Puis j'ai rajouter dans la section versions :

Code:

python-ldap = 2.3.12

Ensuite je lance la commande /bin/builout

et voici mon erreur :
