[Samba] ADS and not working IDMAP on OpenLdap backend

Halo everyone!

I am trying to implement IDMAP backend based on OpenLdap and it refuses to
work. After some diagnostics on both (Samba+Winbind and OpenLdap) sides I
found in my logs following error messages:

Jun  7 14:03:03 proxy slapd[5361]: send_ldap_result: err=21 matched=""
text="objectClass: value #0 invalid per syntax"
Jun  7 14:03:03 proxy slapd[5361]: conn=14 op=3 RESULT tag=103 err=21
text=objectClass: value #0 invalid per syntax
Jun  7 14:03:03 proxy winbindd[5685]: [2006/06/07 14:03:03, 0]
Jun  7 14:03:03 proxy winbindd[5685]:   idmap_init: failed to initialize
remote backend!

Which seems to me, that there might be some bug, or missconfiguration in
somewhere, but I am not able to find it. Of course wbinfo returns nothing
and samba itself is not working...

Could someone throw an eye on following configuration files and see "the
obvious" - reason why it is not working?

Debug information: Samba is running on SuSE linux Enterprise server 9.1 SP
