HTTP Web Server: Lotus Notes Exception - Error validating user's agent execution access

I have an unrestricted agent that is triggered by a document submit via the web. It runs fine in R5 but not in R6. The agent has been edited with the R6 designer and the runtime security is set to allow restricted operations. The server doc lists the agent signer as being able to run unrestricted methods and operations. Julie, if you see this, I’ve read your latest FAQ concerning differences between R5 and R6 agents but I didn’t see anything about this particular problem.
