Four tools that already used flags.Parse (and therefore already had
-proxy registered transparently) still reached out via net.Dial* or
ran DNS resolution past the proxy. Migrate the network calls:
- tools/GetADComputers: custom net.Resolver now dials via
transport.DialContext, so UDP DNS through the DC surfaces
ErrUDPUnderProxy cleanly rather than bypassing -proxy.
- tools/changepasswd: kpasswd TCP dial now uses transport.DialTimeout.
- tools/smbexec: getLocalIP() short-circuits when
transport.IsProxyConfigured(). The "dial UDP to find the local
source address" trick has no meaning when traffic flows through a
SOCKS5 proxy.
- tools/raiseChild: the DNS forest-FQDN fallback (net.LookupHost) is
skipped under -proxy with a message pointing the user to -parent-dc,
since net.LookupHost goes to the OS resolver and would leak DNS.
