Custom variables - all pages go to one visitor, and seems to log only one visitor at a time.

I set up custom variables for the visit and for the page. I pull the LoginID to Piwik, and that is working. However, there are two issues that I am unable to resolve, and can find no answers in all of the searches I have done here for the past week.
Issue 1: If I am logged in, Piwik sees me and logs my page visits, but if someone else logs in while I am logged in, Piwik does not see that person.
Issue 2: Piwik does not see anyone outside of my organization. When a friend logged in from his home, using my login credentials on his pc, Piwik did not see him. When a coworker logged in from his home, using his login credentials, Piwik saw him.
I have spent this week trying to make sense of this, and searching for others who might have this same issue, but without success. Here is my code: I would very much appreciate any suggestions or guidance. Many thanks!
