I am using BO 4.3 & getting error while trying to login in IDT using my user credential with Enterprise authentication, user is member of Administrators so there is no any access/rights issue.
Any idea please? PFA.idt-logon-error.png
Are you using a cluster name or a server name as the system? If you've never logged in to the IDT or other client tool from this computer, your first login needs to be by server name so that it can pull in the cluster information. If that's successful, the appropriate registry entries will be created for the cluster so you can then close the IDT and log in again with the cluster name to actually work in the IDT.
