Zarafa LDAP autentikáció (389-DS CentOS)

Üdv!

A Zarafa Server-t (7.1) tesztlem, mint exchange alternatívát, de ldap-ból szeretném megoldani az autentikációt (389-DS).
Epel repo-ból fent is vannak a csomagok.
A 389-DS ldap be van állítva:

389/tcp open ldap


A Zarafa is be van állítva:

# /etc/zarafa/server.cfg
//...
ldap_host = localhost
ldap_port = 389
ldap_protocol = ldap
//...
ldap_user_scope = sub
//...
// ezt hiányolta, de nem biztos, hogy ez a jó:
ldap_user_type_attribute_value = posixAccount
ldap_hroup_type_attribute_value = posixGroup


A sémát is beincludoltam:

ol-schema-migrate.pl -b /usr/share/zarafa/zarafa.schema > /etc/dirsrv/slapd-rhds/schema/61zarafa.ldif


A "zarafa-admin --sync" hibát ad (log_level=6):

Mi hiányozhat a beállításokban?
Ha ldif-be kiexportálom az ldap-ot, akkor nincsenek benne a zarafa.schema mezői. Ezt furcsállom. A "/etc/dirsrv/slapd-rhds/schema/61zarafa.ldif" automatikusan includolódik, vagy nem?

update:
A zarafa.schema bent van az ldap-ban (389-ds), mert az admin felületen látszódnak a schema-ban definiált zarafaXxxxxxx attributumok.
