I think it is partly some fault of Net::LDAP
Net::LDAP will use IO::Socket::INET or IO::Socket::INET6 to connect depending
on if the inet6 option is passed to connect
::INET will only connect to v4 addresses but I believe ::INET6 will connect to
either. But there is no guarantee ::INET6 exists
Hm, I wonder if we should just select the default connecting class by
my $connect_class = eval { require IO::Socket::INET6 } ? "IO::Socket::INET6" :
"IO::Socket::INET";
