- * The following function exists only to demonstrate the
- * desired functional interface for this routine. You will
- * need to add the appropriate algorithm if you wish to
- * use XDM-AUTHENTICATION-1/XDM-AUTHORIZATION-1.
- *
- * The interface for this routine is quite simple. All three
- * arguments are arrays of 8 unsigned characters, the first two
- * are 64 bits of useful data, the last is 56 bits of useful
- * data packed into 8 bytes, using the low 7 bits of each
- * byte, filling the high bit with odd parity.
- *
- * Examine the XDMCP specification for the correct algorithm
