The Named User's Username appears to be their "Username" in AD. But the participant licenses appear to be their "Email" from AD. Why use two different methods based on cost of licensing? Also is it really their Email or is it their username@domain? Since I need to verify for an AD lookup.
The reason it's confusing is we don't know what we paid for their licensing, or really care. We just want to know who they are, so when we look them up in AD for a lookup, how do we match their account with their login for forms? AD doesn't know how their licensed for Laserfiche to give us a way to determine which field we should match up, username or email.
I have approver lookups all over the place now, with mixmatched login names like domain\user followed by user@domain, and so on. I always thought it was bonkers but just getting around to asking.
