Kerberos error PROCESS_TGS
When trying to sign into MIT SAPgui I got an error "PROCESS_TGS"
What might Kerberos error PROCESS_TGS mean?
Answer
![]() | This answer is not exhaustive - it only lists a cause of Kerberos error PROCESS_TGS which came to our attention. The error might also have other meanings besides what is listed here. |
One situation that can result in Kerberos error PROCESS_TGS is:
- Your computer's clock is at least five (5) minutes wrong, fast or slow.
- You have a computer with Heimdal Kerberos, such as Mac OS X 10.7 or greater.
- You try to connect to a service that uses kerberos, such as SAP.
In that situation, you can get a PROCESS_TGS error. In SAPgui the error text looks like this:
java.lang.Exception: Error: GSS-API(maj): Miscellaneous failure (see text)
GSS-API(min): PROCESS_TGS

Action
The first action is to check the clock on the computer and fix the clock if needed.
On a Mac, you can fix your clock with these steps:
- Go to System Preferences > Date & Time
- Turn ON the checkbox for "Set date and time automatically"
- MIT affiliates can set their time from time.mit.edu
- It is also fine to use a global internet server such as time.apple.com
