I have a user (sheridanpoint) that shows up in the GUI, but does not seem to exit in the back end.
The user exists in the "Switch to user" dialog, though, it shows the error in the image below.
The user also exists in the "Exit user" dialog, but nothing changes in the details below. It still shows the user information that was previously selected, and actually exists.
How can I delete this user from showing up in the GUI?
See image below.
