As far as option D goes I'm now starting to understand IPA makes a distinction between a password and Kerberos keys. If you don't set a password, but use ipa-getkeytab followed by ipa user-show the "Kerberos keys available" attribute changes from Fasle to True, but "Password" remains False. The web GUI doesn't seem to show whether keys were deployed for user accounts and I was expecting to see some indication that I had used ipa-getkeytab, but now see I can only tell using the command line. Can a user have a separate random key as well as a known plain text password simultaneously? Does the krblastpwdchange apply to both password and keys or do keys never expire?
