Can confirm print jobs 'auto-cancelling' with "Local authentication certificate not found" in /var/log/cups/error_log. This is a newly-upgraded dapper client printing to a breezy server via http (on same LAN, no firewalls or other complexities). Upgrading the client to 1.2.1 made no difference.
Upgrading the SERVER to dapper (and thus 1.2.0) also hasn't fixed things but that's another story, see #44931.
