What I would do in your situation is
kinit -c FILE:cachename -k -t FILE:keyfile
and then start your service with KRB5CCNAME set to FILE:cachename
that is your best shot at ensuring that the cache is not accessed by other
services.
FILE:cachename should be in a directory that is only accessible to the
program running kinit and the account that is being used to run your
service.
