Do you have Integrated Windows Authentication checkbox ticked in IE settings?

Hi,

please check if the options defined in the KRB5LoginModule are correct.

First of all check for the option prinicpal. Did you provide this option and also provided the correct value?

This error often occurs if you provided a wrong value for option prinicpal

Cheers
