Univention UCS 4.2 - Failed 'Active Directory Takeover' process - Troubleshooting

[ahernandez]

Hi Moritz, yes, this post is obsolete.

I could move forward to the following point:

Univention UCS - AD Takeover - At least one GPO is still missing in SYSVOL

Using Univention Corporate Server (UCS) and trying to takeover an Active Directory on a Windows Server 2008 R2… Following the guide: https://docs.software-univention.de/manual-4.2.html#windows:adtakeover Section: 9.4. Migrating an Active Directory domain to UCS using Univention AD Takeover I set on my new UCS server, the same values as on the Windows Server 2008 R2 for the following parameters: DNS domain name NetBIOS domain name Kerberos realm LDAP base DN I arrived to the point where I …

but I got stuck there. Then, I could not continue setting up the local domain on my lab.

Maybe someday somebody help me to go forward on that other post.

Just in case it helps somebody, my problem on this post was the case sensitivity of: MYDOMAIN.intranet. I had to be respectful on every place. I think I didn’t take care of the requirment [2] below, recommended on the user guide:

1. The UCS domain controller (master domain controller) needs to be installed with a unique hostname, not used in the AD domain.
2. The UCS domain controller needs to be installed with the same DNS domain name, NetBIOS (pre Windows 2000) domain name and Kerberos realm as the AD domain. It is also recommended to configure the same LDAP base DN.
3. The UCS domain controller needs to be installed with a unique IPv4 address in the same IP subnet as the Active Directory domain controller that is used for the takeover.

Anyway, I had no luck and got stuck on the other post and nobody helped me, so I could not use this amazing tool: UCS 4.2. I think Univention team have created a wonderful tool, though. I hope I can use it someday.

Regards.
