Is that possible somehow?
What exactly are you trying to achieve. You can certainly use the Windows GINA sign-in function for Network Connect auto login.
The same username and password can be used if you create an authentication server instance on your IVE to point to the DC that hosts your users and they can provide their username and password there if that is what you are looking for? Otherwise, it is not possible to not enter credentials of some type for users to login to the IVE.
The closest that is available for that would be certificate authentication in which the IVE requests for a user certificate and the user must select the one to use.
