Using LDAP (or NIS+, or NIS, or passwd/shadow files, or ...  ) will require
a password prompt, something that I think the current design specifically
avoids requiring (I still need to read Owen's doc).

If Kerberos isn't an option, then it would probably be better to work on
something certificate based (SPKM, LIPKEY, etc) that would also avoid the
dreaded pw prompt.  [But now you have a lot more operational challenges.
PKI is way more awful to truly support than Kerberos, IMO.]

Currently, there is no authentication in Hadoop.
