Oh, sure, of course applying a Cisco-recommended "security update" would screw up the network configuration on one of my mailservers that is hundreds of miles away, right before a holiday. And yeah, after getting remote hands to add a cable and reboot, of course it would fail deliverability tests because the software update also broke LDAP queries. I would be tempting fate if I set up a workaround and tried to put it back in service, or worse, if I then proceeded to upgrade the other three to match it so that they could go back to cluster mode. Maybe if I bother them enough tonight they'll give me a security update that is only a security update and not something that turns out to be a broken major feature release.
