So, what happened was this:
We got 4.0.3 ready, thinking that the upgrade strategy was:
samba-tool dbcheck [--fix [--yes]]
The problem is, that in https://bugzilla.samba.org/show_bug.cgi?id=9267
this was contra-indicated - the user lost specific ACLs that they had
We need to work out why that happened, and how to fix that. Sadly it
all happened too late, so we got a bit stuck without an upgrade plan.
Running the new code is fine, but ACLs won't be quite right until we fix
the DB. It should even be possible to drop setting 'acl:search=false',
but as we don't know for sure I really need to dig into this.
This isn't helped by the fact that the samba_upgradeprovision tool is
both amazing in what it does, and amazing in it's internal complexity.
This is a tool that can work out (pretty well) what parts of the
database were created by our provision tool, and what parts were altered
later, and fix errors in that initial provisioning, given new defaults.
Additional complexity also comes from the fact that 'samba-tool dbcheck'
will alter the DB, and so make it potentially harder for
samba_upgradeprovision to run correctly later.
All in all, this is not how we would like it to be, but we hope we can
work this all out soon.
