[jira] [Created] (HADOOP-16526) Support LDAP authenticaition (bind) via GSSAPI

------------------------------------

             Summary: Support LDAP authenticaition (bind) via GSSAPI
                 Key: HADOOP-16526
                 URL: https://issues.apache.org/jira/browse/HADOOP-16526
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
            Reporter: Todd Lipcon


Currently the LDAP group mapping provider only supports simple (user/password) authentication. In some cases it's more convenient to use GSSAPI (kerberos) authentication here, particularly when the server doing the mapping is already using a keytab provided by the same instance (eg IPA or AD). We should provide a configuration to turn on GSSAPI and put the right UGI 'doAs' calls in place to ensure an appropriate Subject in those calls.
