Hi Jason and thank you for your reply.
I'm always used domain_netbios_name\username to login.
I've used now as you suggested UPN test@myexternaldomainname.tld UPN and I put again into GP for local intranet URL of myadfsservername.myexternaldomainname.tld and it works :)
It should be written in mentioned KB's that when user get above error try to logon to workstation using UPN.
Thank you
Best regards
Nenad
