I'm in a kind of odd situation. We have two domains which has two-way trust each other. Some of our employees have domain A accounts, others have domain B accounts, and some others would have both of domain accounts. There would be many scenarios based on business requirements such as "A domain A user can submit forms for domain B user's approval", "A domain B user can submit forms for domain A user's approval."
Origianlly, all of InfoPath form templates and its' workflows are designed for domain A, so there shouldn't be any problem when a domain A user submits forms for domain A user's approval. However, when I assigned an approval task to a domain B account user for the form submitted by a domain A user, Nintex web service (GetRunningWorkflowTasksForCurrentUser) couldn't find any workflow task for the user.
Would you tell me what I should do to get this problem straightened?
