Trying to connect to MS-SQL server on Windows from MacOS

[rockwayschool]

This might be user error... I am running mssql-cli v1.0.0
Names and domains are changed because this is a work computer
mssql-cli -S myserver,myport
I do believe I am successfully connecting to the server, because when I forgot to put the port I got a connection error. After putting in the port, I got a login error.
For the user I put mydomain/myuser. I also tried myuser and \mydomain/myuser
I am on macos monterey. The Directory utility app says I am in AD mydomain.mycompany.us
I have tried both a user created for the db and also my AD SSO account.
I have connected before using both users to this db from windows but I no longer have the laptop.

Am I missing some step in authenticating?

maybe use sqlcmd to test the connectivity. I would facilitate the troubleshooting.
