I need to obtain a user's login name. I have their full name from a simple jquery on a list display page.
The end goal is to create a new list item in another list with a "Person" populated in a "Person or Group" field. I have everything working to create the new list item except the person fields.
I have tried to use "GetUserProfileByName" but that seems to be for going the other way. Any assistance would be appreciated.
