Re: [Samba] Rename domain




Hi,

I'm not sure the domain rename tool will solve your problem.

Currently the rename tool doesn't support the permanent/long-term rename
of a domain. We'd like to support this eventually, but currently the
tool doesn't handle updating the GPO files at all. Currently the
use-cases that the tool supports are: creating a realistic
lab-domain/pre-production testing environment, and providing a
temporary/alternate domain for disaster recovery. You can read more
about the tool here:
https://wiki.samba.org/index.php/Domain_rename_tool
https://wiki.samba.org/index.php/Back_up_and_Restoring_a_Samba_AD_DC

Secondly, we've only been testing the tool against fairly recent Samba
releases. I'm not sure how well it would run against a migrated 3.x->4.x
domain.

Having said that, you could always try running it and see if it works.

Cheers,
Tim
