Connect to External SQL Database using AD User

We have Outsystems installed on PREM. because of Security policy my company doesn't allow SQL user connection. how can I connect to SQL databases(Hosted on PREM) using Active Directory User? 

We tried following connection string "Server=$server;Database=$DB;Integrated Security=True"

APP Pool account running the has proper permission to SQL Database. 

Hi @Bhanuj Soni, try to open port/firewall to a particular host to create a connection

@Aadhavan Shanmugam Firewall port is open. we can connect to SQL DB from that server. from service center we get the error.
