* Fresh Fedora 13 install from DVD, with language and keyboard settings UK.
 * Create local user "dummy" at firstboot since there is no network at this point
 * Login as "dummy"
 * Enable the network
 * Start a root shell
 * yum update
 * yum --enablerepo=updates-testing update auth\*

At this point I have:
  authconfig-6.1.4-2.fc13.x86_64
  authconfig-gtk-6.1.4-2.fc13.x86_64

Default settings:
# authconfig --test

I now try to set up ldap auth in the time-honoured way:
# authconfig \
  --enableldap \
  --enableldapauth \
  --ldapserver=ldap://ldap.virtensys.com/ \
  --ldaploadcacert=http://download.virtensys.com/virtensys-ca.crt \
  --enableldaptls \
  --ldapbasedn=dc=virtensys,dc=com \
  --disablefingerprint \
  --updateall
Starting sssd:                                             [FAILED]


The stock sssd.conf is untouched:
# ls -lrt /etc/sssd
total 12
-rw-------. 1 root root 2829 Apr  2 16:56 sssd.conf
-r--------. 1 root root 1809 Apr  2 16:56 sssd.api.conf
drwx------. 2 root root 4096 May 21 13:25 sssd.api.d


Authconfig does know what the config is *supposed* to be though:
# authconfig --test

If I now fire up the GUI, don't make any changes and click "Apply", it springs into life:
# authconfig-gtk
