samba - Sep 2005 - ads-connect DNS request with DNS type 28 - IPV6??

When i try to connect do my PDC with a net ads join .. i get the following
Error:

  ads_krb5_mk_req: krb5_cc_get_principal failed (No credentials cache
found)
[2005/09/04 09:44:27, 0] libads/kerberos.c:ads_kinit_password(146)
  kerberos_kinit_password root@PVA.SOZVERS.AT failed: Cannot resolve
network address for KDC in requested realm
[2005/09/04 09:44:27, 0] utils/net_ads.c:ads_startup(191)
  ads_connect: Cannot resolve network address for KDC in requested realm
[2005/09/04 09:44:27, 2] utils/net.c:main(873)


In the iptrace i see, that the server tries to do a connect over ipv4 but
he ask for a DNS Type 28 which is as i found for IPV6.

The Server make a dns request of the type 28 - seeDNS Packet breakdown:


  QUESTIONS:
        10.222.33.44, type = 28, class = IN the trace



Has anyone an idea how i can solve this and tell samba that i should not
use ipv6, did anyone have a similar problem?

      Regards
