It looks like there is a problem with the 2.4.4 shield jar in our maven repository.

We are working to fix that - thanks for letting us know.

The maven repository problem has been resolved.

You may need to clear the old jar from any repositories that have a copy of it.

On your local machine that's as simple as deleting the folder .m2/repository/org/elasticsearch/plugin/shield/2.4.4/ from your home directory (something like C:\Documents and Settings\{your-windows-login}\.m2\repository\ ... on windows).

If you are using a local repository manager (like Nexus or Artifactory) you will need to force a re-download there as well.

Can you help me identify the issue

It looks like you have inconsistent spacing in your YAML file.
There appears to be an extra space in front of users:

In the future please post configuration files as code (i.e. preformatted text, using the </> button) rather than a screenshot.

@TimV
Thanks Tim, yes users: was the culprit. It works now.
