I am trying to set up Ubuntu 21.04 to use Active Directory.
I have the VM installed on a ESXi host connected to AD. AD is 2016 schema, on-site, not Azure. The VM does get a correct IP address (I verified in DHCP). The VM does not have internet access, though.
When I get to the point in the install where it asks for username, password, etc., there is an option at the bottom that says "Use Active Directory". Everything I have read says to click that checkbox, but I cannot as it is grayed out.
I have tried this with an an AD object already created, non existent, everything. I've downloaded the ISO and tried a few times now. Is there something that I am missing? I've searched around but it appears this is too new and not a lot of people have tried to mess with it yet.
Thanks
