getDefaults

public static int[] getDefaults(String configName,
                                Config kerberosConfig)

                         throws KrbException

Retrieve the default etypes from the configuration file for those etypes for which there are corresponding keys. Used in scenario we have some keys from a keytab with etypes different from those named in configName. Then, in order to decrypt an AS-REP, we should only ask for etypes for which we have keys.

Throws:

KrbException
