I'm currently running alfresco v6 and authentication of users is done with an AD server. The users in the AD server have now being migrated to the LDAP server. After configuring alfresco with the new LDAP server, the user's associated files are no longer available. The home directory of the users are now empty as well as files the users uploaded to the site. Is there a way to configure my new LDAP with the same users from AD to alfresco?
