Comment 11 for bug 57214

This problem breaks gnome-settings-daemon(crashes), gnome-screensaver(can't unlock), kate(file protocol dies => can't open files) and probably other things as well. Things start working if permissions on /etc/libnss-ldap.conf is set to 644, but it should be 600 becuase it contains credentials.
It's hard to use LDAP this way if nscd isn't working since lookups must be handled through nscd.
