Hello,

I’m using the classic login experience in Winforms (nuget Auth0.OidcClient.WinForms v3.1.2), and the page will load with the message “Please enter your corporate credentials at undefined.”. What property would I need to set to have it not read “undefined”?

The reason I am using the classic login vs the new one is that it does not appear possible to remove the password reset option? I may be missing something there however.

Hi!

it looks like you have a single enterprise connection configured without any **IdP Domains** defined. This can happen with Legacy Lock since it relies on **Identifier First** to display information about the connection.

Go into your Enterprise Connection and set an IdP Domain to fix this issue:

Hope this helps!
