Workcentre 7545 workflow scanning using smartcard credentials

Hi,

We use workflow scanning with a template repository on our Workcentre 7545s (using an SMB file location on Server 2012r2). The users all authenticate with a smartcard before printing or scanning. At the moment we are able to file the scans using credentials stored in a template or typed in directly to the machine. Is it possible to use the smartcard credentials to fole the scans? If so does anyone know what needs to be in the XST file for this to work?

thanks
