I think was fixed, at least in Michael packages... it is not?! There's a
compelling debian bug?

I can totally confirm that.

No. If you go back on list archive, we have discussed and tested this, and
at last i've fired up the bug i've linked.

*Seems* to work, but does *not* work. At least does not work reilable.


Digging a bit deeper, this pose also some performance trouble, because in an
'AD' backend domain members (with or without offline logon/cache enaled) do
an insane amount more of LDAP queries against the DCs then in an 'RID'
backend (with offline logon/cache enaled, of course).


I've not the time/resource to dig deeper in this, but this bug get
introduced by some samba version in advance; the same portable had Ubuntu
16.04 and worked in offline mode as a charm, with the same domain (so in
'AD' mode).
