  • The following article only applies if you are using Microsoft Windows and have the OpenAFS and Kerberos for Windows softwares installed in order to access files and folders in AFS. These are commonly your J:\ and K:\ drives.
    • If you are still using the NCSU Wolfcall application, please note this application is no longer supported. Contact your college or department computer support about getting either OpenAFS/Kerberos for Windows or Expandrive installed on your machine(s).
    • If you are using Expandrive, please refer to the documentation available at the EOS Software site,

Identifying that your Credentials have Expired

  • If you have issues accessing files and folders in AFS from a Windows machine, this can be caused by having missing or expired AFS/Kerberos credentials.
  • To check on the state of your credentials, examine the Network Identity Manager icon in the Notifications tray at the bottom-right of the Windows Taskbar. Figure 1 below shows the different states of the icon.
Figure 1 - Different states of the NIM tray icon
  • In quick summary:
    • Gray - no credentials.
    • Green - Valid credentials.
    • Yellow - Credentials are expiring soon.
    • Red - Expired credentials.
  • If the status is either Gray or Red, you should obtain new credentials using the process outlined below. If the status is Yellow, then the Network Identity Manager may be able to auto-renew your credentials (if that option is enabled), but you can still obtain new credentials yourself if you wish.
  • If the status is Green and you are unable to access files and folders in AFS, contact your college or department computer support for assistance.

Obtain New Kerberos Credentials

 1. Right-click on the Network Identity Manager icon.  See Figure 2.
  • Alternatively, you can go to Start > All Programs > Kerberos for Windows > Network Identity Manager. This will open up the full Network Identity Manager window.
Figure 2 - NIM tray menu
 2. Go to New credentials > Obtain new credentials.  See Figure 3.
  • Alternatively, if you have the full NIM window open, hit CTRL+N on your keyboard.

 3. The New credentials window should appear.  See Figure 4.
  • Be sure the Identity shows as yourUnityID@EOS.NCSU.EDU. If it does not, click on the pull-down menu at the top and select that Identity. If that Identity does not appear, contact your college or department computer support for assistance.

 4. Enter your NCSU password and click OK or FINISH.
  • After the window closes, confirm you can access your AFS mapped network drives. If you continue to have issues, contact your college or department computer support for assistance.
