Subject [jira] [Commented] (ZOOKEEPER-3482) SASL (Kerberos) Authentication with SSL for clients and Quorum
Date Tue, 07 Jan 2020 15:19:00 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-3482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17009816#comment-17009816

Mate Szalay-Beko commented on ZOOKEEPER-3482:

update: I managed to create some working unit tests on the master branch. I tested SASL Digest
+ SSL, and also SASL Kerberos + SSL. So it seems working on the master branch (although due
to some conflict, it requires more work to make the tests work on the branch 3.5). the PR
for the master branch: https://github.com/apache/zookeeper/pull/1204

I want to work now on the 3.5 branch to see if the problem exists there or not. I also want
to reproduce this scenario on a real kerberized server.

>             Project: ZooKeeper
>          Issue Type: Bug
>          Components: server
>    Affects Versions: 3.5.5
>            Reporter: Jörn Franke
>            Assignee: Mate Szalay-Beko
>            Priority: Major

> It seems that Kerberos authentication does not work for encrypted connections of clients
and quorum. It seems that only X509 Authentication works.
> What I would have expected:
> ClientSecurePort is defined
> A keystore and truststore are deployed on the ZooKeeper servers
> Only a truststore is deployed with the client (to validate the CA of the server certificate)
> Client can authenticate with SASL (Kerberos)
> Similarly, it should work for the Quorum SSL connection.
> Is there a way to configure this in ZooKeeper?
> Note: Kerberos Authentication for SSL encrypted connection should be used instead of
X509 authentication for this case and not in addition. However, if it only works in 3.5.5
in addition then I would be interested and willing to test it.
