Enabling Authentication cache on Konica Minolta devices

Overview

  • With Authentication cache enabled, the users authenticating on the printer and their authentication information are stored to the local MFD cache.

  • This allows users to log in to the embedded terminal even when the MFD is unable to communicate with Dispatcher Paragon server and use the native MFD's functions such as copying, scanning or printing from USB.

  • The performed operations are accounted when the connection to server is restored.

  • Feature is enabled by the "Enabling the authentication cache" (authenticationCacheEnabled) configuration property in System Settings in the Dispatcher Paragon web administration.

  • It is also possible to define the period for which the authentication cache is stored (in the "terminalserver.exe.config" file in the key "kmCacheInfoValidatePeriod").

How to configure MFD how to behave in case Dispatcher Paragon server is down

  • Log in to MFD administrator setting as administrator

  • Go to "User Authentication / Account track"

  • Go to "Max allowance when Enhanced Server down" on the 2nd page.

  • Select one of the options

    • OFF - No Limit. User can use service as many as they want.

    • ON - Administrator can set Max limit for each service. When reaching the limit, user is notified with the message on the panel: "The maximum allowance when the external server is down has been reached. Press access to log out. Please contact the administrator."

Limitations

  • This feature is available only for Native Terminal on Konica Minolta devices.

  • MFD's firmware must support OpenAPI 4.2.

  • The first authentication at the printer after the Terminal Server goes offline takes about 30 seconds. Any following authentication is immediate.

  • It is not possible to use this feature with billing codes enabled.

  • It is not possible to use Registration of unknown card feature when MFD is not able to communicate with Dispatcher Paragon system.

  • The cache authentication is available only for card (not PIN, or username+password).

Authentication cache limitations

  • It stores information about max 1000 users.

  • Information are stored for users who once authenticated to the MFD.

  • If more than 1000 user authenticated, the first cached user is replaced with the last user who authenticated as latest (first user stored is the first one out).

  • Retention of the cache is configurable in the device administration.

  • Authentication cache is stored in MFD's internal HDD.

Authentication cache and credit

  • Payments application in Dispatcher Paragon Embedded Terminal for Konica Minolta can not be used with authentication cache enabled. (the fix depends on a third party).

  • Needs to be updated.

  • Authentication cache can be used in combination with Universal Print feature (LK-114) on Konica Minolta's MFDs. More information about this feature can be found in Konica Minolta's manuals.
