SECURING

Assigning SPNs without using the domspnego utility
Use of the domspnego utility is recommended when you want to assign SPNs to one account that multipleIBM® Domino® servers share, which is best practice. If instead you assign SPNs to a separate account for each Domino server, such as the default Local System account, you might want to collect DNS names manually, and have your Active Directory administrator run setspn.exe manually instead, because this case would require the domspnego utility to be run once for each account used.
