Many developers have to install one in order to develop/test Kerberos support in their products.
Is there a distribution that includes a test Kerberos server out of the box, with zero configuration needed?
Ideally it would be available as a VM image.
TurnKey Linux does this kind of things (for instance see their Turnkey Domain Controller), but they unfortunately offer no Turnkey Kerberos.
Must be free, or at least have a free trial period. Ideally open source, but that's not a hard requirement.
Virtualbox-compatible images are best, but otherwise any OS is fine, even hosted or mobile (never know) offers.
