Unable to login to OWA 2013 when require password change is ticked in AD

Hi All

I have a brand new install of Exchange 2013, on server is CAS, the other maibox, this is on a new domain.

I also have a test exchange setup on one server with both roles.

If I create a user in bothe AD and through the ECP and tick the box to require change password at next login, it comes up with

"The user name or password you entered isn't correct. Try entering it again."

If I untick it all is fine.

I have tried the suggestion at this link http://social.technet.microsoft.com/Forums/exchange/en-US/c0dc918d-ccf3-4ada-b4e9-ee44d5903b9e/owa-2013-expired-password-change-not-working

Is there anyone out there that can help or had this issue?

Thanks
