    Description

      When a KDC query is sent, Java uses UDP query first, then TCP.

      The only way of forcing the TCP use is to modify the udp_preference_limit by tweaking a krb5.conf file.

      It should exists a simpler way of forcing the TCP use for these queries. For example, DNS java has this method in its resolver :
      void setTCP(boolean flag)
