@Bhushan kumar What do you mean by ldapsearch not working on Knox? I am assuming that you are trying to do ldapsearch from host where knox is installed and getting "ldapsearch: command not found" which means ldap client utilities are not installed.

Unfortunately the most useful commands for examining this problem are not installed in the docker machine (e.g. ifconfig, netstat, ...) ... View more
