The benefit of providing interactive users with separate batch
principals user@REALM and user/batch@REALM or user/batch/host@REALM
along with associated PTS IDs is that it becomes possible to reduce risk
and improve usage policy auditing.  The batch jobs do not need to be
able to access everything the user is capable of.  For example, a batch
job should not be able to perform an interactive logon and a batch job
probably doesn't have any reason to be accessing the user's home
directories, e-mails, etc.

By setting up batch principals it is possible for the user to initiate
long term tasks that are restricted to certain data sets or perhaps to
certain machines.
