Hi
I am getting exactly the same error as in this thread

Subject : sign-in not found
I am testing in a single forest, multi-domain environment. I have one OCS 2007 Standard server installed in the root domain and have prep'd that and one child domain.
I've been though the documentation and I think I'm ok, but I wouldn't be suprised if I have missed something. Any help would be greatly welcomed
Cheers
Dave
