I have installed Sitecore 8.2.7 couple of times. But recently I figured out that I might have missed the step in the following section, "Windows Authentication for Sitecore".
I am not sure what the "domain user" mean in this context. Is that something we need to create for a Sitecore instance or we can just pick up one of the existing domain user?
I am not even sure if I should choose ApplicationPoolIdentity for Identifier section in Advanced Settings in IIS.
Any thoughts on this?
