We have recently set up 3.1 on a development server and are currently trying to configure NT authentication and SSO for Infoview. NT authentication appears to be working as when Infoview is launched the logon screen appears and allows you to enter you NT logon details. However my understanding is that if SSO is enabled correctly then the logon screen should be bypassed? I have followed all of the BO documentation and looked at various posts on this forum but still no success. Can anyone think of anything we may have missed?
