/**
 * KerberosSecurityTestcase provides a base class for using MiniKdc with other

 * running tests, and stop the MiniKdc (@After) after the testcases, using
 * default settings (working dir and kdc configurations).
 * <p>
 * Users can directly inherit this class and implement their own test functions
 * using the default settings, or override functions getTestDir() and
 * createMiniKdcConf() to provide new settings.
