<% if current_user %>

You should inform the user that they are logged in as <%= current_user.exuid %> and suggest them to <%= link_to 'Log out', session_path, :method => :destroy %> and log in as a different user.

<% else %>

The user will only see this if JavaScript is disabled. Ask them to <%= link_to 'Log in', new_session_path %>.

<% end %>
