[Samba] User disappears, when enabling RC2307

I'm trying to configure a Samba 3.6.6 file server running on a Synology 
NAS to use uid/gid from RFC2307. The file server knows the users from 
the AD, but it does not use the uid stored in the AD. The smb.conf:

         printcap name=cups
         winbind enum groups=yes
         encrypt passwords=yes
         local master=no
         passdb backend=smbpasswd
         wins server=
         winbind enum users=yes
         winbind use default domain=yes
         #winbind nss info = rfc2307
         idmap config AD: range = 1001 - 29999
         idmap config AD: backend = ad
         idmap config AD: schema_mode = rfc2307
         idmap config *: range = 30000 - 50000
         idmap config *: backend = tdb
         load printers=yes
         admin users=@AD\Domain Admins, at AD\Enterprise Admins

This yields:

DiskStation> id mgr
uid=2436891734(mgr) gid=2436891137(domain users) 
groups=2436891137(domain users)

But if I remove the # before "winbind nss info = rfc2307", the user 
disappears. Of course wbinfo -u still has it, but 'id' says it is unknown.

Any idea how to resolve this?

Kind regards,
