Default Trusts
Default Trust records are recreated or edited every time the FactoryTalk Historian
ME starts. This guarantees access to all applications running on the local machine,
even if:

The system’s network configuration changes.

The address changes as a result of a new network card.
The FactoryTalk Historian ME server compares incoming connection credentials
with every trust login record. Each field in a Trust record is compared to the
corresponding credential field. Every field that is not blank in the Trust record must
exactly match the passed credentials. Otherwise, the authorization is not granted.
When an authorization is refused for one Trust record, the FactoryTalk Historian ME
server continues to search the other records until it has exhausted the possibilities.
Client Application Trusts
When using Native security mode, you can create explicit individual Trust records for
each client application or you can group them according to subnet address, host
machine, or user name. A group of applications can share the same privileges, based
on matching a name in the user database.
The FactoryTalk Historian ME supports trusts for the following client applications:
