This command just instructed kinit to renew the TGT in the cache
$KRB5CCNAME.  Does such a cache exist?  Is there a valid TGT in the
cache?  Is the TGT renewable?

You just asked to list the contents of the default ccache.
Is this the same as $KRB5CCNAME?
Was there anything in the cache to begin with?
