I have MOSS working in one partner, but I'm going to add a MOSS to another partner.
I'm just not 100% sure on one issue. A collegue was under the impression that the MOSS site could only be joined to the external domain because the external domain trusts the users from the other two. However, it is my understanding that because MOSS is setup just like a .NET 2.0 app (claims app) then that shouldn't matter.
I have .NET 2.0 apps in all three domains, and everyone can get to everything. The caveat was that while the two internal domains are trusted by the external, the external is not trusted by the internals. So I simply created my federation trusts to be internet based, not forest trust based. After a few kinks of forgetting I had to specify the correct suffix, everything is working.
MOSS should simply be a .NET 2.0 like app and so I should be able to set them up and not have shadow accounts or anything, because it's not a windows token based app.
Is that correct?
