------------------------------------
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.
