Public bug reported: A configuration that works perfectly after setup prevents an Ubuntu 12.04 Precise client from booting.
Checks before rebooting: 1. winbind authentication is working (console login, xrdp, etc) 2. libnss-ldap name resolution is working (getent passwd) (this is the intended setup) After booting the default Grub option we see the machine hung without printing anything. Booting in recovery mode allows us to see that the last printed message is: Begin: Running /scrips/init-bottom ... done. The problem IS related to libnss-ldap because if we boot via cdrom and change nsswitch.conf to use local authentication the machine boots again perfectly. We can then change it back to use local authentication + ldap (compat ldap) and verify that it works. However the system won't come up after rebooting. Even though the nss_initgroups_ignoreusers is correctly setup there is provavly some service that is trying to use ldap before networking is available. The extra options (see below) intended to lower timeouts seem to have no effect.
