[Samba] Winbind doesn't honor rfc2307 data set in AD (Samba 4.3.6 on Debian jessie)

Hi all, I've just installed Samba 4.3.6 on Debian jessie amd64 (as
described in the wiki [1]) and everything seems to work properly
except for rfc2307 data that winbind doesn't retrieve from AD backend,
shell is always "/bin/false", homedir is always
"/home/DOMAIN/username" and "getent passwd" also lists user without
unix attributes.
I have configured idmap_ad as described here [2] with rfc2307.
Hereafter my configuration:
# cat /etc/samba/smb.conf
[global]
log level = 5
workgroup = VBOX
realm = VBOX.LOCAL
netbios name = ARTURO
interfaces = lo eth1
bind interfaces only = Yes
server role = active directory domain controller
idmap_ldb:use rfc2307 = yes
allow dns updates = nonsecure
dns forwarder = 192.168.0.1
idmap config *:backend = tdb
idmap config *:range = 2000-9999
idmap config VBOX:backend = ad
idmap config VBOX:schema_mode = rfc2307
idmap config VBOX:range = 10000-99999
winbind nss info = rfc2307
winbind trusted domains only = no
winbind use default domain = yes
winbind enum users = yes
winbind enum groups = yes
[...]
# cat /etc/nsswitch.conf
passwd: compat winbind
group: compat winbind
[...]
# getent passwd

# getent group

The user VBOX\dhcp has no unix attribute set but it is still listed
with an uid-number outside "valid" range:

What have I misconfigured?
