Trying to sign into SAPgui, but get error window:
Set ATHENA.MIT.EDU as the default realm for Kerberos tickets
This error message often indicates that your Kerberos tickets are for a realm other than ATHENA.MIT.EDU. In some areas of MIT, such as CSAIL or the Media lab, Kerberos tickets may be configured with a default realm of CSAIL.MIT.EDU or MEDIA.MIT.EDU. This will prevent access to SAP, and cause the above error.
Follow the steps on this page to set the correct default realm.
For win.mit.edu machines, ensure that you are logged in to ATHENA.MIT.EDU domain
- On login, select ATHENA.MIT.EDU (Kerberos realm).
- Consultants have seen the above error message result when users select the WIN option at login on a win.mit.edu machine.
- If you are logging in to the local machine, make sure that you enter your MIT Kerberos account username (the part of your MIT email address before the @mit.edu), and that the default realm for the Kerberos tickets is ATHENA.MIT.EDU (see instructions above).
