Connect and maintain connection to socks5 proxy server with authentication - go

Question

I'm trying to dial using credentials and maintain a connection with a socks5 proxy server in Go.
This works nicely if I have IP authorisation set up with the proxy provider, however there is no way pass any auth credentials using net.Dial function in Go:
package main
import (
"io"
"net"
)
func main() {
dst, err := net.Dial("tcp", "11.22.33.44:1111")
if err != nil {
panic("Dial Error:" + err.Error())
}
dst.Close()
}
Go has a useful proxy library and allows authenticated forward requests via proxy using this:
package main
import (
"io"
"net"
)
func main() {
var proxyAuth *proxy.Auth
if conf.Username != "" {
proxyAuth = new(proxy.Auth)
proxyAuth.User = conf.Username
proxyAuth.Password = conf.Password
}
proxyconn, _ := proxy.SOCKS5("tcp", "11.11.11.11:1111", proxyAuth, nil) //returns a Dialer with proxy that can be invoked to connect to another address
dst := proxyconn.Dial("tcp", "22.33.44.55:6666") //connects to an address via proxy
dst.Close()
}
However it returns a Dialer that then asks to connect a target/ultimate address through this authenticated proxy rather the proxy server itself:
My objective here is to return a net.conn connection with a credentials-authenticated proxy server - something like this:
package main
import (
"io"
"net"
)
func main() {
//net.Dial does not have a way to pass Auth creds
dst := net.Dial("tcp", "22.33.44.55:6666", proxyAuth)
dst.Close()
}

The net.Dial() method doesn't concerned with proxy authentication. However, If you want proxy authentication you can set it in header of the request before the call. Please refer this link
dst := net.Dial("tcp", "22.33.44.55:6666")
