"No such file or directory" for unknown reason

[02strich]

Migrated from 02strich/pykerberos#24

I'm getting this:

Traceback (most recent call last):
  File "/usr/local/lib/python3.5/dist-packages/django_auth_kerberos/backends.py", line 51, in check_password
    kerberos.checkPassword(username.lower(), password, getattr(settings, "KRB5_SERVICE", ""), settings.KRB5_REALM)
kerberos.BasicAuthError: ('No such file or directory', 2)

1.1.5 runs fine, 1.1.6 has the error from #12 which is fixed in 1.1.10, which shows this error here. KRB5_SERVICE is empty, but, as i said, 1.1.5 runs fine.
