Thanks Steve for your quick response. Securing of the data is not a major concerns for us (at-least for now). Once a user is authenticated, he/she is already inside our secure zone.
The issue that we often face is, that we have 100+ dashboards from various departments all users have write access to it. Again, we are not so concerned about the "read" part as of now.
Just by the looks of it, we have to hack the Kibana 4 source code or we write a wrapper to go on top of it with a reverse proxy or something.
Please let me know if you have any workable suggestions for now. I would rather not touch the code base, just because I don't want to get stuck with a version of the product. We want to be able to upgrade as the newer versions started to show up.
Btw, Is there a way for me to write a plugin for it? (Although readme document in the plugin directory says not to do that!! ).
