USER ID PLACEHOLDER

This will replace "[email protected]" that's shown as a hint in the user ID input field on the Azure AD login page.

* Important: you should only configure this if you only support internal users. If you expect external users to sign in to your app(s), we recommend you leave this blank (Azure AD will show "[email protected]").
