Give staff ID of duplicate user when staff account username or external ID matches one in the system
When you are adding an account or changing information on an account and the system detects a duplicate, it won't let you proceed. However, it won't give you any information on the conflict account.
It would be super helpful to have the conflicting ID shown in the popup message to make tracking down the other account easier.
Especially if the dup happens to be because of something weird like a space or non-printable character.
This seems to happen more as locations move to SSO and fill in their external ID field.
