A couple of months ago I joined a few Windows 11 workstations to a Samba DC. This weekend when I tried the same it failed. Apparently all Wndows 11 with the latest updates will not join or log into a Samba DC.
Has anyone else experience this issue?
What version of Samba is the DC running ? There was a problem with Windows 11 and kerberos, but this was fixed quite some time ago, so your fix might just be to update Samba.
