The publisher user is called psu. this user shouldn't run the task. In section access I can only set use "ntname" or user password. the task should be run with user "Domainx\user1" or if this isn't working with user: "Publisher" (not a domain user).
Only specific ntuser should be able to open up the file (don't want to have password), so I need the section access with ntname.
DOMAINX\USER1 can open the application as long as logged in as DOMAINX\USER1 PUBLISHER, will have to enter PUBLISHER/PUBLISHER to enter but the login is irrelevant.
However, if reloading in Publisher, see the section in the Publisher manual on how to configure Section Access with Publisher reloads.
