I used a turnkeylinux.org otrs installation and I'm trying to configure the default domain of 'yourhost.example.com'. I tried the following:
sed -ri 's/yourhost.example.com/mydomain.com/' /usr/share/otrs/Kernel/Config/Defaults.pm sudo shutdown -r now
The next time I logged and tried to create a user, the default domain was still there.
How can I change default doamin in an OTRS installation?
