No. This is to enforce things like password policy expiration
times.  The old code would apply the password expiration
policy for our domain to trusted users.

I'll go back and check tomorrow.

No.  You're not listening.  The child for our domain
only has BUILTIN, LOCALMACHINE, and DOMAIN in the domain_list.
This is because the child is forked in order to answer the
initial getTrustedDomains request by the parent.  The child
needs to obtain the password policy from the trusted DC
when a user from the trusted domain logs on even if the
authentication is handled by our DC.

Here's my example:

* box is a member of AD
* AD has a two way trust with COLOR
* COLOR\gcarter logs in to the member server via ssh.
* The password policy for AD (no expire) is applied to
  COLOR\gcarter even though the password expire in
  COLOR is set to 30 days.

Sure.  I understand.  I'll go back and run the test and
if necessary fix it so that we get the policy from the
correct domain.
