>>Do you know if the username used by Active Directory (AD) is unique in the AD? This is the username (along with the password) that a person enters into his/her PC when logging in.

https://www.zubairalexander.com/blog/the-strange-way-in-which-active-directory-implements-the-full-name-attribute/Thank you for the article. I use both the AD username and the display name. The table in my app that stores all users didn't have a column for the AD username before. And at that time the display name had to be unique. Now I added the AD username - for some customers. And since the display name for these customers can be the same I ran into an issue. This is what I am troubleshooting. But endless support calls yesterday and today won't let me concentrate on resolving the problem :) This is what the weekends are for :)
