NethServer Version: 7.9.2009
As title says, the latest nethserver-dc update deletes all of my users and groups.
Looks like the active directory is still intact.
I was going to try a configuration backup and restore, and my nethserver-backup-config fails, and I have created another topic about that.
Here’s a thread about a not working nethserver-dc update, maybe some of the suggestions are helpful in your case…
