Description Arvid Requate

2018-09-06 12:53:32 CEST

When changing the IP address, e.g. via

ucr set interfaces/eth0/address=10.200.8.50

or via DHCP, the Heimdal KDC doesn't bind to the new IP address. The same applies to the Samba/AD builtin KDC. I guess we will have to add a restart script like we have for univention-directory-listener and univention-s4-connector in

/etc/network/if-post-down.d/

The if-post-down.d script alone did not help: After reboot and receiving the address via DHCP, kinit still failed. Looks like something is out of order there.

I've added a workaround for this in our test config files. Please remove it once the issue is fixed: 45f29d83
