[Samba] One Way Domain Trust possible?

[Birger Schacht]

hi,

the release notes of samba4.3 read:
"The support for trusted domains/forests has improved a lot."
and
" Both sides of the trust need to fully trust each other!"

is this still true for samba 4.5 or is it possible to create a one way
trust from DC domain A (samba) to DC domain B (windows)? i've looked at
the samba 4.5 release notes, but didn't find anything about trust
relationships in there...
(background: i want to run a DC 'A' with samba but use the accounts from
another DC 'B', which is not under my management. There is no trust from
DC 'B' to DC 'A')

thanks in advance,
Birger
