This is on a machine that is 4 years old, running F12.
$ uname -a
Linux eblake 2.6.31.12-174.2.22.fc12.i686 #1 SMP Fri Feb 19 19:26:06 UTC 2010 i686 i686 i386 GNU/Linux

Or even trying to run successfully.  I created the following tmp.conf:

listen_tls = 0
listen_tcp = 1
tls_port = "16514"
tcp_port = "16509"
listen_addr = "192.168.0.1"
mdns_adv = 0
mdns_name = "Virtualization Host Joe Demo"
unix_sock_group = "libvirt"
unix_sock_ro_perms = "0777"
unix_sock_rw_perms = "0770"
unix_sock_dir = "/home/eblake/libvirt"
auth_unix_ro = "none"
auth_unix_rw = "none"
auth_tcp = "sasl"
auth_tls = "none"
key_file = "/etc/pki/libvirt/private/serverkey.pem"
cert_file = "/etc/pki/libvirt/servercert.pem"
ca_file = "/etc/pki/CA/cacert.pem"
crl_file = "/etc/pki/CA/crl.pem"
tls_no_verify_certificate = 1
tls_allowed_dn_list = ["DN1", "DN2"]
sasl_allowed_username_list = ["joe EXAMPLE COM", "fred EXAMPLE COM" ]
max_clients = 20
min_workers = 5
max_workers = 20
max_requests = 20
max_client_requests = 5
log_level = 3


then ran:

$ daemon/libvirtd --pid-file=pid-file --config=tmp.conf
16:17:16.754: error : remoteConfigGetAuth:2564 : remoteReadConfigFile: tmp.conf: auth_tcp: unsupported auth sasl


Ideas of what to do next?  Maybe the test should be reordered
to first attempt testing an unmodified conf file, and only if
that succeeds, then rip through the list of one-per-line corruptions?
Am I missing some setup or packages to get SASL support enabled?
