There's no direct way to do this from a Template.  You need a Script 
containing:

raise 'LoginRequired'

...which you can call from the Template using:

tal:define="foo here/raiseLogin"

You could also use DTML to raise the exception, if you wanted.  It's too 
bad that LoginManager doesn't provide a method that you could call to 
raise the exception.
