We found out it has to do with GPO. With
ad_gpo_access_control = enforcing
we get failures (system error 4 with no indication in the logs it was GPO in any way).
ad_gpo_access_control = permissive
and all is well. I’ll open a ticket with Canonical.

You should file a bug in Ubuntu, specially if downgrading to the previous package fixes the problem for you.
