Kerberos Error Messages on a Macintosh

Even with a correctly configured Kerberos setup, it is still possible to run into problems when trying to access Kerberos-controlled network services. Information about some of the standard Kerberos error codes is provided below.

Note: SideCar will not work on any Macintosh computer with an Intel processor, or any Macintosh computer manufactured after June 2006. On these machines, there is often no error message, but the system fails to authenticate.

Error code 3

If you are using a Macintosh and you receive an Error code 3, it probably means the clock on your Macintosh is set incorrectly (either the time or the time zone). The Macintosh is unable to obtain the correct time from the Kerberos ticket server to compensate for the clock error. To set the clock, go to the Date & Time System Preference and reset your clock to the correct time. If the problem persists, search for and throw out the edu.mit.kerberos file that is usually in the Users->yourusername->Library->Preferences folder. Empty your trash and restart your machine.

Error code 5

If you are using a Macintosh and you receive an Error code 5, it means you are using an incorrect password. The error text in the dialog box says Sorry, your password is incorrect. Please try again. Check to make sure the [Caps lock] key is not set. Verify that you are using the correct password.

Kerberos error 62: Password incorrect

If you are entering the correct BlitzMail password, but are still receiving a password incorrect error, change your BlitzMail password. The reason for this is arcane and fairly technical. To put it simply, BlitzMail uses an authentication process that may allow you to sign on if the password you type in is "one letter off" from your real password (for example, substituting an "m" for an "n"). So, you may be able to sign on to BlitzMail, but not able to sign on to other authenticated services.

If you are unable to change your password, please contact the IT Service Desk (Help Desk) at 646-2999 and select from the options provided, send electronic mail to help@dartmouth.edu, or call your department's IT support office.

Kerberos error 79 and 81

If your DND name is longer than 38 characters, you will receive error 79 or error 81 from Kerberos. There is a limit to the length of your DND name in the Kerberos software. If your full DND name is longer than 38 characters, please contact the IT Service Desk (Help Desk) at 646-2999 and select from the options provided, send electronic mail to help@dartmouth.edu, or call your department's IT support office. Your DND name will need to be shortened.
