Subject [jira] [Commented] (AMBARI-6432) FreeIPA Support in Ambari
Date Fri, 18 Jul 2014 15:31:06 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-6432?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14066441#comment-14066441

jay vyas commented on AMBARI-6432:
----------------------------------

*I've just gotten some feedback from the FreeIPA folks, summarizing their thoughts inline
here:*

a) Authentication into Ambari
http://www.freeipa.org/page/Web_App_Authentication

b) Security and identity of the stack
FreeIPA can provide
- centralised management  for service accounts and their keys and certificates, and they
- smart proxying 
- use FreeIPA as hub for management system to connect + hosts that would be clients/hadoop
slaves
See http://theforeman.org/manuals/1.5/index.html#4.3.11FreeIPARealm as an example + http://projects.theforeman.org/projects/foreman/wiki/RealmJoinIntegration

The next steps for this task would be to draw all the connections between the components (masters,
slaves) and how they communicate.

> FreeIPA Is a powerful tool for unifying identity, kerberos credentials, across a cluster.
> A great value add for ambari would be to provide support for using FreeIPA to kerberize
services.  This would allow for 
> 1) better HCFS interoperability, because first class GID/UID is critical for certain
file systems (GlusterFS, Lustre, and any other file system which uses kernel / FUSE apis for
determining identity)
> 2) better enterprise interoperability.  Because of the fact that FreeIPA makes it easy
to interop with different identity solutions (like active directory), it would make ambari
easier to adopt for various enterprises.
> 3) broadens ambaris scope.  Now ambari could also allow people to setup the users of
their clusters, and at least some of the security features of their clusters, all from one
interface (no more manual handling of TGTs and such - it could all be done quite easily via
the ambari UI which could make calls to underlying FreeIPA clients).
