SELinux is disabled, I changed the permissions back to the old ones and I have the problem again, although as root I can kinit as myself and can run commands. But not as the regular user. Do you have any strace examples to share?

When you use ls with the -Z option there is a '?' where the SELinux context should be printed. Maybe there are issues with your SELinux setup which prevent access to the ccache files? Can you try SELinux in permissive mode? If there are still issues running klist which strace might give some more details why the ccache file cannot be read.
