i creating python service data mssql server, , connection string goes follows,

connection_string = 'driver={sql server native client 11.0};server=192.168.2.45;database=dialogic;uid=smsuser;pwd=sms;'

when tried host same service on linux machine , returning error saying client missing , followed documentation , installed connecting-to-sql-server-from-rhel-or-centos per steps.
