An interoperability issue is found between Java and the native Kerberos implementation on BSD (including macOS) on the kdc_timeout setting in krb5.conf, where Java interpreted it as milliseconds and BSD as seconds when no unit is specified. This code change adds support for the "s" (second) unit. Therefore if the timeout is 5 seconds, Java accepts both "5000" and "5s". Customers concerned about interoperability between Java and BSD should use "5s".
