I configured the ldap authentication following this guide (http://www.ochounos.com/#blog/6). It imported in Alfresco all users from ldap, but I can't login in Alfresco with user/password stored in Ldap. There is no error in alfresco.log or catalina.out so I don't have any idea of why it doesn't work.
Also, I deleted in Alfresco one user imported from ldap and this user is not synchronized anymore (alfresco doesn't import it).
Do you have any idea of what could be the problem?
