Thanks for the quick reply.
Tried a more specific targeted OU
BASE DN - OU=Personal Accounts,DC=trusted,DC=com (remote trusted domain)
With or without the No anonymous referral chasing, the return is:
“Your LDAP config seems OK, 0 User objects found”
On linux systems joined to the local trusting domain with Power Broker or
SSSD/Realm joining them to the domain we are able to lookup users from the
remote trusted domain.
