Worked here, but that wasn’t easy. Take care :
- File server module was removed somewhere in the procedure, probably at step 1. Dunno why.
- It has to be reinstalled BEFORE reinstalling the AD. I had to retry some times to get AD and File server installed correctly.
- Password policy was reset to “Strong password required” at some point
- Just in case somebody wonders : Groups have to be restored AFTER users.
- Permissions were lost on shared files, I had to “Reset Permissions”
- All password were wrong after import, maybe because at some point (after having exported the user.tsv file) I did a yum update for some bad reason.
All in all, it might be easier to reinstall completely to change the FQDN because this change is really huge and currently error prone.
