Apparently Java's Kerberos implementation does not
support using TCP connections to obtain Kerberos tickets.
This is required when using Windows 2003 Active Directory
as the KDC because the Kerberos tickets must include all
of the Windows ACL data.  The Kerberos tickets are therefore
larger then the maximum size of a UDP packet.
