I have been using Dev Tools to copy them semi-successfully. It is tricky because there is a lot of copying to be done and I am not the only one doing it, so explaining the Dev Tool method to others comes across as foreign.

The reason so much copying is being done is because you can't trust AD usernames, their username can be domain\samaccount or first last@domain or email. Because of this I tell everyone to copy from the Forms Admin page now instead of Active Directory, I seem to remember never having a problem copying directly out of the browser.

Edit:

The need for an ability to select a user I would guess, after assisting with hundreds of processes, is about 25% of all forms processes across all customers. So given the popularity of this, wouldn't it make the most sense to have a lookup that self references the forms database for active accounts? The reason I normally do not do this is because I don't have control of changes to this database and an update could break this. Maybe a built in reference to accounts could be added?

With LFDS becoming available for Avante systems, we hope to move all user management to LFDS which would fix the issue of the different usernames vs emails vs AD names. As organizations move to LFDS, their user management in Forms will be greatly simplified and more uniform.
