[Samba] samba winbind forest one way trust issue

[Firxiao zhang]

Hi all,
below is my lab environment, I want to using *CHILD 's users for
authentication. I * tryed create Forest1 and Forest2 2-way-trust, and
tested samba3 and samba4 just work fine. *but if I change 2-way-trust to
1-way-trust. the winbind3&4 would lost the Forest1's child domain trust.
  does winbind support forest one-way-trust?  or I missed some
configuration?  *
*also I search a lot of same question about this but do not seen an
official answer. *
Any help would be gratefully appreciated. Thanks!

work fine:
