Subject [jira] [Commented] (AMBARI-6432) FreeIPA Support in Ambari
Date Wed, 02 Mar 2016 17:05:18 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-6432?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15175992#comment-15175992
] 

Denys Buzhor commented on AMBARI-6432:
--------------------------------------

This is because *createKerberosSiteObj: function (site, tag) {* called 2 times with different
site and tag, for _kerberos-env_ and _krb5-conf_.

Since *kdc_type* property included in *kerberos-env.xml* _properties\['kdc_type']_ will be
absent in *krb5-conf* as a result *kerberos-env* properties will be updated by *tweakManualKdcProperties*
and *tweakIpaKdcProperties*.

> 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).
