Trying out the latest business edition of clearOS, my purpose is to migrate active directory users and their policies to clearOS.
I have installed “Active directory connector “,
I get error on “Authentication Error”,
The time are same on the both the server, dns names given to AD I can ping and it is able to resolve it

I would like to trouble shoot and find the reason.
I am checking the log file location, /var/log, did not see any change of files contents there
How could I know what is happening during the authentication. It is neither showing at windows server or in clearOS machine
Guidance and advice requested.
