Your well-informed and quite thorough advice is much appreciated. I had seen vague references to environment variable troubles in various mailing list archives but thank you for spelling it out so explicitly and providing the test cases. However, it looks like the problem was caused by an outdated build of MPIg as the delegation of the credentials began working after it was upgraded to the latest version (although one of the 1000 tweaks I made while troubleshooting the problem might have made a difference). I'm still waiting on final confirmation that everything is working correctly but, given that these systems will be used for a demo at SC07 and the close proximity of that event, I'm pretty sure I would have heard some screaming if it wasn't fully functional.
