Can you query multiple LDAP sources for user authentication?

I’ve added a trusted forest. But cannot seem to authenticate it against the trusted forest.

I can swap LDAP connections and it works, but I can never authenticate against the trusted forest connections.

Thoughts ?

You will need to have Web UI(s) configured to authenticate to domain A and different WebUI(s) that are configured to authenticate to Domain B. We use this configuration to support multiple domains without issue.
