yes - when attempting to access the service it shows the expected login 
screen.

confirming that the authentication succeed with an already expired TGT 
seems not intuitive to me. i understood the spec in the following way: 
"a login screen or something similiar is requested when the user doesn't 
have a valid TGT".

but good to know it's not a bug ...

Cheers,
Frank
