安装完MIT Kerberos的客户端后，krb5的目录是一个隐藏的目录，这点很恶心
Setting Up the Kerberos Configuration File
Settings for Kerberos are specified through a configuration file. You can set up the configuration file as an .ini file in the default location, which is the C:\ProgramData\MIT\Kerberos5 directory, or as a .conf file in a custom location.
normally, the C:\ProgramData\MIT\Kerberos5 directory is hidden. For information about viewing and using this hidden directory, refer to Microsoft Windows documentation.
