Authentication against AD

Hello guys,

We recently deployed the Rocket Chat on our Ubuntu server (14.04 LTS) using snap. On trying to configure it to authenticate against the AD, I am constantly get the error when I do TEST CONNECTION. Screenshot of logs attached.

I am sure with the setting values like host, baseDN, userDN etc. as we are using same for multiple web apps.

It is almost a week now and I am still struggling to get it work. Will appreciate any help or suggestion.

It looks more like it can’t connect to the port rather than an AD DN path issue.
