 User Authentication Tickets (MFP models only)
When using User Authentication to connect to the MFP from a PC client station, the user must be
authenticated using the User ID and password information sent to the MFP. However with the use of
pre-issued User Authentication Tickets, users can access the MFP without having to input the
necessary authentication information each time a session is initiated.
First, to be issued a User Authentication Ticket, the user connects to the Integration Server from a PC
client station, at which time authentication is performed using the User ID and password. Once the
server authenticates the user, the ticket is sent to the MFP. When user then accesses the MFP, e.g. to
download stored images or perform other operations, the ticket is sent from the PC client to the MFP
along with the request to initiate a new session. The MFP then communicates with the Integration
Server to verify the identity of the user.
