Description Erik Damrose univentionstaff 2016-11-14 12:10:55 CET
When using an app appliance with fast demo mode, a preconfigured LDAP is shipped in the appliance. When updating ip address settings in system setup, the host DNS settings are not correctly updated.
Comment 1 Erik Damrose univentionstaff 2016-11-14 12:19:39 CET
I adapted net_apply to behave differently when fast demo mode is configured in the appliance, which updates the DNS settings correctly.

I also added network bridge ports to the blacklist of ethernet devices. Otherwise, the preinstalled apps docker bridge would be configureable in system-setup

r74390 univention-system-setup 9.0.5-5.998.201611141215
r74391 yaml
Comment 2 Erik Damrose univentionstaff 2016-11-15 16:27:19 CET
r74449 Do not blank screen when system-setup is running
r74450 yaml
Comment 3 Erik Damrose univentionstaff 2016-11-17 17:23:23 CET
Worked well in my tests -> resolved

r74549 Merge to ucs 4.2
Comment 4 Alexander Kläser univentionstaff 2016-12-08 14:29:22 CET
In r74390, you changed MODULE.info('Running script %s\n' % scriptpath) to MODULE.error(...). Please revert this line.

r75120 univention-system-setup 9.0.5-7.1000.201612081449
r75122 yaml

It was already correct in ucs 4.2
Comment 6 Alexander Kläser univentionstaff 2016-12-08 15:31:59 CET
I observed a few other 10.203.* network entries in the LDAP (notably the SSO entry and the default DHCP DNS policy). As this does not lead to direct problems, I opened Bug 43140.

Otherwise, the installation + docker app work as expected. Network bridge ports are not shown in the setup wizard. I did not see a blank screen during the setup procedure.

Changes: OK
YAML file: OK
Merge to 4.2-0: OK
