I'd like to make a report of all sites in all of my web applications, and store site owners in one of columns. I am using PowerShell.
I can retrieve the owners using $Root.AssociatedOwnerGroup.Users
The problem is that when I try to create a SPUserValue object, to store it the People and Groups column, it requires a user ID, which is relative to the site.
Is it possible to store user information from different sites, or even web applications?
