Your SQL Linux has been joined to domain and you can connect to the SQL Server instance using Windows Authentication.
The connection itself is fine, but when you run some high privilege T-SQL statements like 'Create Login' , 'sp_addsrvrolemember' , you may run into the issue 'Error 15404 ‘Could not obtain information about Windows NT group/user '%ls', error code 0x80090304''
When you run queries like 'create login', it will cause permissions to be checked. The first time you do it, it invalidates current permission. When you do it again, the permission check will be rechecked. When doing the permission check, SQL Server has to go through the mssql.keytab to pick up the machine entry key or MSA key. If SQL Server does not find the entries or find invalid entries, it raises error in question.
Here are three common scenarios that will cause the issue.
1.The machine account entries are not added. (mssql.keytab is configured by machine account)
