Can you give me a pointer to the major differences that have
evolved over time? I know many of the calls and structures
in s3 suck, but in my pretty recent attempts to modify them
I produced a considerable amount of crashes and memleaks, so
morphing that code to me at least is a tricky task. In
particular the non-existing proper talloc hierarchy is a
major obstacle that needs VERY careful fixing. But that is a
task completely separate from adding a s4 auth module.

A separate auth module to connect to S4 (similar in spirit,
maybe not the implmentation to the auth_netlogond module) is
very welcome!
