This guide will document necessary assumptions and requirements if you would like to set up your ECMT install to authenticate for users across two different Active Directory (AD) domains.
Assumptions
You are only wanting to use ECMT across two different Active Directory domains.
...
You cannot have two users from the different domains with the same username. For example, there cannot be a “jsmith” in AD1 and also a “jsmith” in AD2.
Requirements
AD1 will need to have the ECMT application installed and configured with AD Sync via Admin -> System Settings -> Active Directory Settings. Once installed and configured, a Two-Way Trust will need to be established between AD1 and AD2.
...
Users from both domains should be synced automatically as ECMT users if they are a part of the AD Synchronization Group.
Example Group Setup
