Hi, I am trying to deploy tackle in a web farm, but I get an error below.

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

I search in google and found the random key generator that I can use in the <machineKey> element, since I'm not an experienced developer I need help on how to fix the error.

Unfortunately I've never done any testing of Tackle in a web farm so I have no experience on how to fix this - maybe someone else out there has?
