Hi,

First of all thanks a lot for kerberos plugin .

I am trying to setup SSO for our ELK stack. We are using ES 2.1.1. I downloaded the plugin from your repository.

While installing I am getting the following error. I hope you I would get some help from you.

elkadmin@svlitcpp$ sudo ./plugin install file:///usr/share/elasticsearch/bin/elasticsearch-shield-kerberos-realm-2.1.1.zip --verbose

-> Installing from file:/usr/share/elasticsearch/bin/elasticsearch-shield-kerberos-realm-2.1.1.zip... Trying file:/usr/share/elasticsearch/bin/elasticsearch-shield-kerberos-realm-2.1.1.zip ... Downloading .DONE Verifying file:/usr/share/elasticsearch/bin/elasticsearch-shield-kerberos-realm-2.1.1.zip checksums if available ... NOTE: Unable to verify checksum for downloaded plugin (unable to find .sha1 or .md5 file to verify) ERROR: Could not find plugin descriptor 'plugin-descriptor.properties' in plugin zip

I am not having the clue where went wrong. Am I downloading wrong plugin version for for elasticsearch 2.1.1 or something wrong I am doing ? Please guide me.. it is quite urgent use case for us at the moment.

Thanks,
Prakash.
