What Wyllys said.

The Samba team can go and do what they like -- there's plenty of KDC
source code with sufficiently friendly licensing to go around.  But I'd
much rather see cooperation (and cooperate) in the design of pluggable
interfaces for KDCs, such as pluggable backends, pluggable
pre-authentication provides, and pluggable authorization-data providers
(particularly AD-KDCIssued containees), and later, when extensions comes
along, pluggable ticket extensions providers.
