Clicking on the login tile of a user that has already authenticated with an Windows Password but not an AuthAnvil passcode asks for a passcode only. This happens even after the logon screen has returned to the Ctrl-Alt-Del prompt.
This behavour is by design.
Due to the way that the login process works with AuthAnvil for Windows Server 2008, to more easily allow users to authenticate, after a valid logon ID and password are entered, but an invalid Passcode is entered, the logon session is kept active until one of the following conditions is met.
Note: This will also persist through screens requiring a Ctrl-Alt-Del.
- The user successfully logs on
- Another user successfully logs on
- The computer is reset
