2475 * KFW_KRB4_life_to_time - takes a start time and a Kerberos standard
2476 * lifetime char and returns the corresponding end time. There are
2477 * four simple cases to be handled. The first is a life of 0xff,
2478 * meaning no expiration, and results in an end time of 0xffffffff.
2479 * The second is when life is less than the values covered by the
2480 * table. In this case, the end time is the start time plus the
2481 * number of 5 minute intervals specified by life. The third case
2482 * returns start plus the MAXTKTLIFETIME if life is greater than
2483 * TKTLIFEMAXFIXED. The last case, uses the life value (minus
2484 * TKTLIFEMINFIXED) as an index into the table to extract the lifetime
2485 * in seconds, which is added to start to produce the end time.
