Deleting device certificates

  1. At the command prompt, type one or more of the following:

    • For unsecured printers

      DDUAppFolder\bin\ddu ‑deleteDeviceCert ‑ip IP

    • For secured printers

      • Basic authentication method using user name, password, or PIN

        DDUAppFolder\bin\ddu ‑deleteDeviceCert -ip IP ‑usr UserName ‑pwd Password ‑pin PIN

      • Kerberos authentication method

        DDUAppFolder\bin\ddu ‑deleteDeviceCert -ip IP ‑usr UserName ‑pwd Password ‑rlm RealmName ‑rlmType KERBEROS

      • LDAP authentication method

        DDUAppFolder\bin\ddu ‑deleteDeviceCert -ip IP ‑usr UserName ‑pwd Password ‑rlmType LDAP ‑rlmSetup RealmSetupName

      • LDAP + GSSAPI authentication method

        DDUAppFolder\bin\ddu ‑deleteDeviceCert -ip IP ‑usr UserName ‑pwd Password ‑rlm RealmName ‑rlmType LDAP_GSSAPI ‑rlmSetup RealmSetupName

    where:

    • DDUAppFolder is the location of the DDU folder.
    • IP is the IP address or host name of the printer. To restart multiple printers, use commas to separate multiple IP addresses or host names.
    • UserName is the user name for accessing secured printers.
    • Password is the password for accessing secured printers.
    • PIN is the PIN for accessing secured printers. This option is applicable only to the basic authentication method.
    • RealmName is the Kerberos realm name when using Kerberos or LDAP + GSSAPI authentication method.
    • RealmSetupName is the setup name configured on the printer when using LDAP or LDAP + GSSAPI authentication method.
  2. Check the progress of the deployment in the DDU status window.
Note: The printer reboots after you delete the device certificate.
