About Accessing Cross-Domain Historian

You can now access Historian across various domains regardless of the domain to which your user account belongs. To do so:

• Ensure that all the domain controllers across various domains trust one another.
• Create iH security groups on each leaf node that contains the Historian server that you want to access.
• Ensure that you are part of at least one iH security group. You can be part of an iH security group directly, or you can be part of a universal domain group, which must be part of the iH security group.
