NEW: Add compatibility for IPv6
FIX: Properly fix display of IPv6 ips in the logs

Reverted
ERROR instead of INFO

fixes #2132
Made a nicer message

With a little clarification: if voms returned an actual error, then there is a real problem. If it's just because voms-proxy-init isn't present, then only show the notice.
Fixed res -> result

Also conventions.
