Since realmd is the same, it's samba that had the bug and it was fixed in later releases, so from focal onwards the problem is not present. It looks like it was https://bugzilla.samba.org/show_bug.cgi?id=14007, fixed in 4.10.9. Since Ubuntu 19.10 Eoan is EOL, and 20.04 has 4.11.6 and I just confirmed it works there. I'll mark this bug as fix released then. ** Bug watch added: Samba Bugzilla #14007 https://bugzilla.samba.org/show_bug.cgi?id=14007 ** Changed in: realmd (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853572 Title: realm fails with option --computer-ou To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/realmd/+bug/1853572/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
