Hello all We have an AD domain A.COM that has a child domain 1.A.COM 1.A.COM has a two-way, non-transitive external trust (ie separate forest) with another domain B.COM Should I be able to use AD POSIX credentials from 1.A.COM on a Linux machine running winbind (idmap backend ad) in B.COM? That is our desire.
