LDAP Importing and Domain Trusts

Hello,

RT 5.0.2, hosted locally, using ldapimport to pull users from a single domain into rt, no issues for many years now.

Recently we setup an AD trust with another organization and I am interested in pulling those users into RT and applying permissions based on group memberships as we do today.

Typical configurations in RT_SiteConfig.pm.

How might I best go about this?
