I’ve been trying to enable YCQL authentication in order to create roles within a local Yugabyte cluster. I’ve entered the docker container running yugabyte by using the command “docker exec -it --privileged bash”, and then running “./bin/yb-tserver --fs\_data\_dirs “/home/yb-tserver-dir” --use\_cassandra\_authentication=true”. However, I’m getting an error saying “bash: lsof: command not found”. Is there another way that I should be enabling YCQL authentication?

Notes: I followed the steps here under the Docker tab to install Yugabyte and create the local cluster: [YugabyteDB Quick start for macOS | YugabyteDB Docs](https://docs.yugabyte.com/latest/quick-start/install/).

Solved: Used the command “./yb-docker-ctl create --use\_cassandra\_authentication”.
