Prerequisites

  • The end user will need to have their c- account already created by an IT admin and be in the correct initialization state.

  • The end user of the c- account and Smartcard/YubiKey should be the one performing these steps.
    • Exception is made for non-ITS Staff, faculty, and/or vendors.

  • YubiKeys get 10 attempts at logging in before it automatically locks. Afterwards it can be reset by contacting ADTT@syr.edu

  • Best practice is to log out of anything using your c- account beforehand if you previously were issued a Smartcard/YubiKey

Steps to setup a Smartcard / YubiKey

Using a AD managed Windows computer:

  1. Use RDP (Remote Desktop Connection) to connect to the server smartcard.syr.edu

  2. When prompted for Logon, 
    1. If you are RENEWING YOUR YubiKey: use your current YubiKey to log onto the server.
    2. If you are SETTING UP A YubiKey: You received an email from "Smart Card Manager" with a username and password. 
      1. After opening RDP, select "More choices" and log in as a different account. Use the username: c-netid (example: c-testuser or AD\c-testuser) and the password from the email.

  3. On the desktop of the server find the "Setup Smartcard" icon in the upper left and double click on it.

  4. A command prompt will open,
    1. If not already inserted, plug the YubiKey into a USB port on the computer.

  5. The process is now underway and can take a few moments.

  6. A new window will appear. Press "More Choices". Select the YubiKey option (looks like a small credit card icon) from the list if not already selected.
    1. If the window appears and there is no option for a YubiKey and PIN, but rather it asks for a smartcard to be connected; be sure the smartcard is inserted correctly into the USB drive and also that the RDP session allows smart card passthrough. To turn on smart card passthrough, close out of the Smartcard Setup window and logout of smartcard.syr.edu. Open RDP, go to Show Options/Local Resources/More... and make sure "Smart Card" is checked.

  7. Enter the default PIN of the card. 
    1. If you are RENEWING YOUR YubiKey: use the PIN you have set on the smartcard.
    2. If you are SETTING UP A YubiKey: use the default PIN 123456

  8. You will be prompted again for the SAME PIN a few moments later for the root certificate to be added so the YubiKey is more versatile. 

  9.  After, you can sign out of the RDP session. (Go to the Start Menu, click the silhouette of a person just above the Start Menu, Sign Out)

  10. Once completed you will not be able to log into any server directly with the username and password like what was done in step 2. You will need to use the Smartcard and pin. (The smartcard should show up under "More Choices" when using RDP)

  11. Remove and Reinsert the YubiKey in the usb port before trying to use it.
    1. If you just renewed your smartcard, you may need to reboot your system before the Kerberos protocol can utilize the smartcard subsystem.

YubiKey's for Non-ITS Staff, faculty, and/or vendors

  • The IT unit that manages the YubiKey end user should order the YubiKey or receive it from the user if they are providing their own.

  • The IT unit can then complete the setup of the YubiKey on behalf of the user by contacting ADTT@syr.edu. 

  • After the card is setup, it can be given, or mailed, to the user with instructions on how to set the PIN.

Setup and Reset Requests for Non-ITS users

  1. If the request is to setup a new card:

    1. The DSP should have the physical card with them
    2. Make contact with ADTT@syr.edu and ADTT will find a time to help the DSP setup the card in the name of the user
      1. (Optional) After the account is created and the card is setup, the DSP can add the c- account to whatever groups the user may need
    3. The DSP can deliver the card to the user, please verify the actual user receives the card, and explain how to change the PIN (Change Smartcard PIN) 

  2. If the request is to reset a smartcard:
    1. The DSP can collect the card from the user, reset the card (Reset YubiKey / Smartcard To Factory Default), and contact ADTT@syr.edu 
    2. We ADTT will assist in resetting the card just like the steps above.

Changing the PIN on the Smartcard

If the YubiKey is still using the default PIN of 123456, it will need to be changed before the end user can access Syracuse University resources. Instructions for changing the pin on your Smartcard are found here: https://answers.syr.edu/x/JTfLBw

General Troubleshooting

  1. Make sure the YubiKey is inserted correctly into the USB port. The USB-A style YubiKey's can fit in a USB port both ways. When inserted correctly, the "y" on the card will flash green.

  2. The gold medallion on the YubiKey is actually a touch button. Pressing/touching it prints a OTP (One-time password) and presses Enter. (This is not used currently, but may be used in the future)

  3. If you are not able to log into the server during step 2 two due to "Access Denied" warning, contact ITS, your account likely has SmartcardLogonRequired = true.

  4. If you are waiting for a prompt to appear to enter a PIN for an exceedingly long time (wait>20s), click on the CMD window an and press Enter twice. ElseIf this does not resolve, please contact ITS.

  5. (Windows) Under Device Manager on your computer, check the Smart Cards setting for a Yubico Minidriver. 
    1. If the driver is not present and the computer you are on is DOMAIN JOINED restart the computer and check again. Else, contact ITS for help.
    2. If the driver is not present and the computer you are on is NOT DOMAIN JOINED, you will need to download the driver manually from Yubico's website (https://www.yubico.com/products/services-software/download/smart-card-drivers-tools/). 
      1. To get to the driver download you can: Go to yubico.com>Support>Downloads. Find the CAB Download for the Yubico minidrivermini-driver. When the minidriver mini-driver is downloaded, extract it to a folder and Right click the .inf file>Install.
      2. After the driver is installed, the computer may require a restart.

  6. (Windows) If you are receiving the error: "The client has failed to validate the domain controller certificate for _______. The following error was returned from the certificate validation process: A certificate chain could not be built to a trusted root authority." AND the computer you are on is NOT DOMAIN JOINED. It may mean the computer you are on does not trust the root certificate from AD. Please contact ADTT@syr.edu for help trusting the cert.

  7. (Mac OS) Macs may macOS) Apple computers may not be able to use the card after setup. This is because of NLA, when . When the Mac tries to connect to RDP it requires a username and password before the smartcard Smartcard is used. Thus making it not work. To get around this, the Mac Apple computer should log into a Windows computer (such as a VM) and rdp us RDP from there, so you may select . This allows the selection of the Smartcard/YubiKey from "More Choices"

  8. (Mac OSmacOS) Mac Apple computers using the rdpRDP/remote client application to remote into servers should make sure they are on Version 10+.

  9. (Mac OSmacOS)  Assuming the remote client application is version 10+, when using the smartcard Smartcard the first time to configure it, if it does not show up as an option the connection likely does not pass Smartcards. To resolve, exit the connection, right click it in the rdp RDP client application and select Edit. Under the devices tab, make sure Smart Card is checked. Re-enter the session and try again.
