It's Kopano, formerly known was Zarafa. With version 4.1.13 it seems that simple binds were still possible, but that actually might have been an error while developers aim to emulate a real AD server. In the meantime I managed to bind with a LDAP browser over TLS or SSL, but the mailserver still fails in connecting to AD.
