Can't login with domain user

[BenIA]

Hi,

I've just upgraded to 8.1.

I was always able to login as a different user and use my work network user credentials i.e. workgroup\username. On this version I can do this. I can only add users once logged in and switch between them on the login screen.

This version doesn't show the 'login with different user' link. I've looked around the settings, but haven't had any luck with getting it to appear on the login screen.

Any advise on this would be very welcome.

Cheers.
