Many functions use low-level socket interface for connection or various checks. However, most of the time we don't respect automatic address family detection but rather try to force our values. This may cause either redundat connection tries when an address family is disabled on system tries or even crashes when socket exceptions are not properly caught. Instead of forcing address families to socket, rather use getaddrinfo interface to automatically retrieve a list of all relevant address families and other connection settings when connecting to remote/local machine or binding to a local port. Now, we will also fill correctly all connection parameters like flowinfo and scopeid for IPv6 connections which will for example prevent issues with scoped IPv6 addresses. bind_port_responder function was changed to at first try to bind to IPv6 wildcard address before IPv4 as IPv6 socket is able to accept both IPv4 and IPv6 connections (unlike IPv4 socket). nsslib connection was refactored to use nss.io.AddrInfo class to get all the available connections. Socket is now not created by default in NSSConnection class initializer, but rather when the actual connection is being made, becase we do not an address family where connection is successful. https://fedorahosted.org/freeipa/ticket/2913 https://fedorahosted.org/freeipa/ticket/2695

Code to be installed on any client that wants to be in an IPA domain. Mostly consists of a tool for Linux systems that will help configure the client so it will work properly in a kerberized environment. It also includes several ways to configure Firefox to do single sign-on. The two methods on the client side are: 1. globalsetup.sh. This modifies the global Firefox installation so that any profiles created will be pre-configured. 2. usersetup.sh. This will update a user's existing profile. The downside of #1 is that an rpm -V will return a failure. It will also need to be run with every update of Firefox. One a profile contains the proper preferences it will be unaffected by upgrades to Firefox. The downside of #2 is that every user would need to run this each time they create a new profile. There is a third, server-side method. See ipa-server/README for details.
