> I tried setting up Kerberos on my laptop which has the hostname 'todd-Thinkpad-T540p' (including capital letters). It seems like we are inconsistent about our treatment of caps -- if I make the keytab with the principal kudu/todd-thinkpad-t540p it fails complaining it can't find kudu/todd-Thinkpad-T540p, and if I make the keytab as the latter, it fails complaining it can't find the former.
