I try to access my samba4 AD DC using Kerberos authentication. The following command works nicely on the DC itself, given that Administrator has a ticket. But it fails on the client machine:

root@samba4:/# host samba
samba.ad.microsult.de has address 172.16.6.240
root@samba4:/# host samba.ad.microsult.de
samba.ad.microsult.de has address 172.16.6.240
root@samba4:/# host samba.uac.microsult.de
samba.uac.microsult.de has address 172.16.6.240
root@samba4:/# host 172.16.6.240
240.6.16.172.in-addr.arpa domain name pointer samba.uac.microsult.de.

Is there any way to stop GSSAPI from the reverse lookup?

I use the MIT flavor libraries. Is it probably better using Heimdal?

See:

http://web.mit.edu/kerberos/krb5-devel/doc/admin/conf_files/krb5_conf.html

The rdns and dns_canonicalize_hostname options should control dns lookups.
