> Without the FQHN in /etc/hosts Kerberos and AD integration with

I agree with Mathieu and just want to underline that if any application
fails with a static /etc/hosts containing
127.0.0.1 localhost
127.0.1.1 <UNIX hostname>
then it's the application that needs to be fixed.

Title:
NetworkManage does not set domain in /etc/hosts on DHCP connections
Status in “network-manager” package in Ubuntu:
Won't Fix
Bug description:
Binary package hint: network-manager
When NetworkManager start a DHCP connection it sets IP and hostname in
/etc/hosts, but it does not include the FQHN. Without the FQHN in
/etc/hosts Kerberos and AD integration with windbind do not work.
Example: After setting up a DHCP connection NetworkManager adds this
line on to of /etc/hosts
161.42.184.214 wkjpvtest # Added by NetworkManager
For Kerberos and winbind to work correctly, the line should be:
161.42.184.214 wkjpvtest.ads.krz.uni-heidelberg.de wkjpvtest #
Added by NetworkManager
The following short NetworkManager hook, solves the problem for me
now:
#!/bin/sh -e
# Dirty hack to set the FQHN in /etc/hosts for DHCP connections managed
# by NetworkManager, install it in /etc/NetworkManager/dispatcher.d/
HOST=`hostname`
DOMAIN=`grep domain /etc/resolv.conf | cut -d' ' -f2`
# first check if the domainname is already set
if ! grep -q "$HOST.$DOMAIN" /etc/hosts ; then
# if not, correct /etc/hosts to include the FQHN
sed -e s/"$HOST.*# Added by NetworkManager.*"/"$HOST.$DOMAIN &"/ /etc/hosts
> /tmp/hosts.new
mv -f /tmp/hosts.new /etc/hosts
fi
