Bonjour à tous,Je travaille actuellement au déploiement de Liferay 5.1.1 couplé à un Alfresco Labs 3.0a avec authentification basée sur un OpenLDAP.L'ensemble du déploiement se passe correctement jusqu'à la configuration d'Alfresco pour une authentification LDAP.Dans le détail la structure donne :- Linux Red Hat Entreprise- Tomcat 6.0- Liferay 5.1.1 déployé en mode WebApp (sur une base MySQL 5.1)- Alfresco 3.0a déployé en mode WebApp (sur une base MySQL 5.1) avec déploiement de Webscripts dans Liferay- OpenLDAP- Liferay configuré en authentification LDAP.- Alfresco configuré en authentification BDDJusque là tout se passe correctement.Lorsque je positionne les fichiers ldap-authentication-context.xml, ldap-authentication.properties, ldap-synchronisation-context.xml et ldap-synchronisation.properties dans le répertoire {AlfrescoPath}/WEB-INF/classes/alfresco/extension/ et je redémarre le Tomcat, j'obtiens le message d'erreur suivant :ERROR [web.context.ContextLoader] Context initialization failed

You can also use JAAS authentication for Kerberos against Active Directory or NTLM if you also require single sign on from the
web browser. You do not have to use LDAP authentication to synchronise groups and users from an LDAP store if it supports other
authentication routes, like Active Directory.

This maps between what the user types in and what is passed through to the underlying LDAP authentication.
"%s" - the user id is passed through without modification.
Used for LDAP authentication such as DIGEST-MD5, anything that is not "simple".
"cn=%s,ou=London,dc=company,dc=com" - If the user types in "Joe Bloggs" the authenticate as "cn=Joe Bloggs,ou=London,dc=company,dc=com"
Usually for simple authentication. Simple authentication always uses the DN for the user.

# This properties file brings together the common options for LDAP authentication rather than editing the bean definitions
#
# How to map the user id entered by the user to taht passed through to LDAP
# - simple
# - this must be a DN and would be something like
# CN=%s,DC=company,DC=com
# - digest
# - usually pass through what is entered
# %s
ldap.authentication.userNameFormat=cn=%s,ou=Users,ou=Alfresco,dc=company,dc=com
# The LDAP context factory to use

# The URL to connect to the LDAP server
