A Kerberos ticket
is required to open SAPgui. To get a Kerberos ticket:
Staff Laptops on the MIT domain (set up by MechE IT):
- Kerberos tickets are generated automatically by computers on the MIT domain (which asks for a username and password during logon).
- Staff Windows Laptops set up by MechE IT should be able to launch the SAPgui program after activating the VPN.
- If you get an error message, please double-check you are connected to the VPN. If errors persist, follow the instructions below to install Kerberos for Windows.
Create a Kerberos Ticket by following the instructions:
SAPgui may bring up the Ticket Viewer to prompt you to obtain Kerberos tickets. If not:
- You may see an error mentioning "GSS-API"
- SAPgui may stall at "Connecting..."
- Your SAPgui session may freeze.
All of these behaviors mean that either you do not have Kerberos tickets, or your Kerberos tickets have expired. To resolve that issue, use the instruction below to get tickets manually.
How to get Kerberos tickets manually
- Launch Kerberos Ticket Viewer (/Applications/Utilities/Ticket Viewer). On Mac OS Catalina it is located in (/System/Library/CoreServices/Applications)
- Enter your Kerberos username (the first part of your @mit.edu email address), and your Kerberos password (the password used to check your @mit.edu email).
NOTE: Your Kerberos tickets will last for 10 hours only, and have to be manually renewed if you wish to remain in SAP longer. If you do wish to remain in SAP longer than 10 hours, it's a good idea to renew them at least 20 minutes or so before they expire.
