        Description

        According to the doc [1]:

            ...you can instead specify these values by setting the
            following system properties to indicate the realm
            and KDC, respectively:

                java.security.krb5.realm
                java.security.krb5.kdc

            If you set values for these properties, then they override
            the default realm and KDC values specified in krb5.conf (if
            such a file is found). The krb5.conf file is still consulted
                                                      ******************
            if values for items other than the default realm and KDC
            are needed.

        However, in code of sun.security.krb5.Config [2]:

        122 String kdchost =
        123 java.security.AccessController.doPrivileged(
        124 new sun.security.action.GetPropertyAction
        125 ("java.security.krb5.kdc"));

                        ....

        137 if (kdchost != null) {

                        .... using system properties as settings ....
                        .... and do NOT read config file anymore ....

        151 } else {
        152 // Read the Kerberos configuration file
        153 try {
        154 Vector<String> configFile;
        155 configFile = loadConfigFile();
        156 stanzaTable = parseStanzaTable(configFile);
        157 } catch (IOException ioe) {
        158 // No krb5.conf, no problem. We'll use DNS etc.
        159 }
        160 }

        The JDK does not read the properties in the file : /etc/krb5/krb5.conf.
