Description Nico Gulden univentionstaff 2017-03-01 12:22:57 CET
See user feedback at Ticket#2017022421000167.

Background: The user already had a UCS system joined into a Microsoft Active Directory domain. He deleted the system. The records in AD remained. The join of another system failed because of these left overs.

The forum has the solution: http://forum.univention.de/viewtopic.php?f=48&t=3889&p=14035#p14008

The documentation should be extended by a hint for testers to avoid a research and enable them to avoid this pitfall.

I'd rather see this in SDB.
Comment 2 Arvid Requate univentionstaff 2017-03-07 11:56:29 CET
To make this Bug findable in Bugzilla precise core keywords are essential:

If the SRV record _domaincontroller_master._tcp is already (or still) present in the DNS domain zone of the Active Directory nameserver, the setup of the AD connection (aka member mode) doesn't work.

We should improve the user experience though directly in the software to avoid this frustration factor right from the start. I've opened Bug 43745 for this.

This happens fairly often, there are several reports on help.univention.com. Today we had a potential customer in sales with this problem.
Comment 4 Florian Best univentionstaff 2017-09-01 11:43:13 CEST
I think we will fix the real problem instead of showing a hint. Bug #42918
