'Authentication for Hadoop HTTP web-consoles ... via LDAP?

I want to limit access to the Hadoop web UIs. But I don't want to set up Kerberos. We have LDAP, though.

Looking around, I see:

  1. Authentication for Hadoop HTTP web-consoles
  2. Class LdapAuthenticationHandler

I like to think I could somehow stuff the LdapAuthenticationHandler into the Web Authentication stuff, but it is not obvious, and I can not find an example.

Is what I am seeking possible?

Failing that, I could set up HTTP proxies that do basic auth via LDAP. If I do that, does the user ID information get relayed to the Hadoop web UIs? (I am thinking specifically of the HDFS file browser.)
