SOLVED: "AuthenticationSupport service missing. Cannot authenticate request."

Question

A customer was installing CQ5 on a Red Hat Linux environment, and getting the following error displaying in the browser.
AuthenticationSupport service missing. Cannot authenticate request.
We checked the Felix Console, and all bundles were installed correctly.
We did however find the following message in the error log:
20.06.2012 10:49:26.689 *ERROR* [FelixStartLevel] org.apache.jackrabbit.core.RepositoryImpl failed to start Repository: Unable to register data store in cluster. javax.jcr.RepositoryException: Unable to register data store in cluster.
Caused by: java.net.UnknownHostException: {server name}: {server name}
This was not a clustered instance.
On closer inspection, the error was caused by an incorrect IP address entry for {server name} in the hostnames file

Hello Mkiti,
    I take a look there and my host file only contains comments :s
    Heres the content:
# Copyright (c) 1993-2009 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host
# localhost name resolution is handled within DNS itself.
#    127.0.0.1       localhost
#    ::1             localhost
    The error only happen after I install the CQ5 update fix, from package share. I just renamed the crx-quickstart folder, the CQ create a new one and works, but my projects still in the old quickstart :s Is there a way to physically copy these projects, maybe?
