Finally, I had some breakthrough today. The original issue was with the way bind dn was provided in the config. Once I corrected it, I was able to see the ADDING BLOCK message. Once that was corrected, then I was able to login using my domain id and it was authentication and authorized based on rules setup. This was also a bit of trial and error. Normally, we login with domain\userid. But i have to use just user for this to work.
The only other thing pending now is to get the monitoring working. As per Elastic, monitoring will work only with no-security or with x-pack security. Once I have ROR, as per them, it wont work. Is that a true statement?
Below is the update from Elastic team member.
I have another thread open for this. Feel fee to reply directly on that thread.
Thanks again for all your help!
