I have a way to solve what I need for now, so this is a curiosity with this connection. I have two users with the same name in my organization. Let's say Jane Doe. Both have unique user ids. I first get the logged in user domain\LoginId. Then, I Set the Account Name, Run the Query and Set Employee Fields. The fields even set correctly for the Department and a few others. But, when the user hits submit, it fails with a validation on the name that shows in the Employee people picker field. It works for everyone else except Jane Doe. For now, I've simply changed the rules to everyone except Jane, run the rules. Has anyone bumped into this before? If so, what did you do to solve? Thank you!

Is this a list form? I'm asking because I'm curious about the validation failure....

I apologize for not responding sooner. It is a library form. It's a little strange because the user login id is different for both. I still just have a specific rule in place for this one end user.
