KDC won't start after fresh install

[Sebastian Singer]

Hi,

I have been installing Kerberos form scratch on a Debian Wheezy this day 
following http://techpubs.spinlocksolutions.com/dklar/kerberos.html .

Double checked everything but when trying to start KDC this is what the 
log says:

/var/log/kerberos/krb5kdc.log:
Sep 05 13:12:52server.net krb5kdc[22172](debug): Got signal to request exit

Sep 05 13:12:52 server.net krb5kdc[22455](info): commencing operation

I opened ports 88, 464, 749 and 750 in iptables for udp and tcp. Still 
no clean server start.
I wonder if there is something  with ipv6 as in line 9 of the log it 
refers to "socket address ::"?
I hope it is just a beginner's mistake ;-)

Every bit of help is appreciated.
Yours,
Sebastian
