RDP "Other user"?

Question

RDP

Good afternoon!
Help me to understand.
There is a RDP server on Windows 2008 p2
In the security settings of the Remote Desktop Host, "RDP security level" is selected
In local policies:
Interactive logon: do not display the last username - enabled
When connecting to a server with already saved data: domain\username\ password - the "Other user" window appears, I poke it and a form appears where the name / password is entered. It is
necessary to make it so that you can connect with the already saved data.
Willing to answer additional questions.
Thank you!
