Gregory Chanan updated SOLR-9200:
---------------------------------
Attachment: SOLR-9200.patch
Here's a new version of the patch, taking into account [~ichattopadhyaya]'s
comments. In particular:
1. All security related znodes have been moved under /security
2. The existing ZkACLProviders now derived from SecurityAwareZkACLProvider,
which by default does not allow read only access to znodes under /security for
non-solr users.
3. Moved all kerberos-related test setup from KerberosTestUtil to
KerberosTestServices. This object does "all in one" setup, i.e. dealing with
non-supported locales, kdc setup, Configuration management. It also handles
resetting the Configuration at the end of the test, so other tests in the same
jvm can run successfully.
4. Got rid of extra imports.

> SOLR-7468 added support for kerberos authentication via the hadoop
> authentication filter. Hadoop also has support for an authentication filter
> that supports delegation tokens, which allow authenticated users the ability
> to grab/renew/delete a token that can be used to bypass the normal
> authentication path for a time. This is useful in a variety of use cases:
> 1) distributed clients (e.g. MapReduce) where each client may not have access
> to the user's kerberos credentials. Instead, the job runner can grab a
> delegation token and use that during task execution.
> 2) If the load on the kerberos server is too high, delegation tokens can
> avoid hitting the kerberos server after the first request
> 3) If requests/permissions need to be delegated to another user: the more
> privileged user can request a delegation token that can be passed to the less
> privileged user.

> I made the following comment which I need to investigate further, since I
> don't know if anything changed in this area:
> {quote}3) I'm a little concerned with the "NoContext" code in KerberosPlugin
> moving forward (I understand this is more a generic auth question than
> kerberos specific). For example, in the latest version of the filter we are
> using at Cloudera, we play around with the ServletContext in order to pass
> information around
> (https://github.com/cloudera/lucene-solr/blob/cdh5-4.10.3_5.4.2/solr/core/src/java/org/apache/solr/servlet/SolrHadoopAuthenticationFilter.java#L106).
> Is there any way we can get the actual ServletContext in a plugin?{quote}
