Subject [jira] [Updated] (HADOOP-10307) Support multiple Authentication mechanisms for HTTP
Date Fri, 06 Jun 2014 17:12:02 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-10307?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Benoy Antony updated HADOOP-10307:

    Attachment: HADOOP-10307.patch

Taking a different approach for this feature. 

_CompositeAuthenticationHandler_ is added.
* _CompositeAuthenticationHandler_ accepts multiple _AuthenticationHandler_  via configuration.
* When processing an authentication request, it picks up the _AuthenticationHandler_ based
on url parameter “authtype”.
* If “authtype” is not specified, it uses the default _AuthenticationHandler_(first one
in the configured list of Authentication Handlers).
* For no-Browser access, there can be a separate _AuthenticationHandler_. This logic is borrowed
from _AltKerberosAuthenticationHandler_.

*Note 1*: _CompositeAuthenticationHandler_ offers the features of AltKerberosAuthenticationHandler.
In addition, it allows configuring any number of AuthenticationHandlers. Based on the parameters
and header values, it delegates control to the appropriate AuthenticationHandler.

*Note 2*: _AnonymousAuthenticationHandler_ is added. With this handler, Anonymous access is
achieved via a fixed account. Once can restrict the anonymous access privileges by restricting
the permissions of the anonymous account.
