Uploading a Kerberos configuration file
1
From the Embedded Web Server, click Settings > Security > Security Setup.
2 Under Advanced Security Setup, click Kerberos 5.
3 Click Browse, and then select the krb5.conf file.
4 Click Submit to upload the krb5.conf file to the selected device.
The Embedded Web Server automatically tests the krb5.conf file to verify that it is functional.
Notes:
• Click Reset Form to reset the field and search for a new configuration file.
• Click Delete File to remove the Kerberos configuration file from the selected device.
• Click View File to view the Kerberos configuration file for the selected device.
• Click Test Setup to verify that the Kerberos configuration file for the selected device is functional.
Setting date and time
Because Kerberos servers require that key requests bear a recent time stamp (usually within 300 seconds), the printer
clock must be in sync or closely aligned with the KDC system clock. Printer clock settings can be updated manually, or
set to use Network Time Protocol (NTP), to automatically sync with a trusted clock—typically the same one used by the
Kerberos server.
1 From the Embedded Web Server, click Settings > Security > Set Date and Time.
2 To manage the settings manually, type the correct date and time in YYYY-MM-DD HH:MM format, and then select
a time zone from the drop‑down menu.
Notes:
• Entering manual settings automatically disables the use of NTP.
• If you select (UTC+user) Custom from the Time Zone list, then you will need to configure additional settings
under Custom Time Zone Setup.
3 If daylight saving time (DST) is observed in your area, then select the Automatically Observe DST check box.
4 If you are located in a nonstandard time zone or an area that observes an alternate DST calendar, then adjust the
Custom Time Zone Setup settings if necessary.
5 To sync to an NTP server rather than manage date and time settings manually, select the Enable NTP check box,
and then type the IP address or host name of the NTP server.
6 If the NTP server requires authentication, then select the preferred method from the “Authentication” menu, and
then click the Install MD5 key link or the Install Autokey IFF params link to browse to the file containing the matching
NTP authentication.
7 Click Submit to save the changes, or click Reset Form to restore the default settings.
