Issue with mssql docker linux container

General

Hi I was wondering if someone else has had this issue before,
Currently trying to authenticate with LDAP using How to Enable AD Authentication for SQL 2019 Containers in Less than 5 Minutes | Data Exposed - YouTube as a guide with Configure Active Directory authentication with SQL Server on Linux-based containers using adutil - SQL Server | Microsoft Learn

the only thing different i changed is the docker compose file which im not sure if thats the issue,
I was checking the logs and couldn’t find information of the issue
the only issue im having is when i try to create the user

the ad server is 192.168.3.80

create login [domain\administrator] From Windows


Msg 15401, Level 16, State 1, Line 1
Windows NT user or group 'domain\administrator' not found. Check the name again.
