- * Ticket lifetime. This defines the table used to lookup lifetime
- * for the fixed part of rande of the one byte lifetime field. Values
- * less than 0x80 are intrpreted as the number of 5 minute intervals.
- * Values from 0x80 to 0xBF should be looked up in this table. The
- * value of 0x80 is the same using both methods: 10 and two-thirds
- * hours . The lifetime of 0xBF is 30 days. The intervening values
- * of have a fixed ratio of roughly 1.06914. The value 0xFF is
- * defined to mean a ticket has no expiration time. This should be
- * used advisedly since individual servers may impose defacto
- * upperbounds on ticket lifetimes.

- * krb_life_to_time - takes a start time and a Kerberos standard

- * The second is when life is less than the values covered by the
- * table. In this case, the end time is the start time plus the
- * number of 5 minute intervals specified by life. The third case
- * returns start plus the MAXTKTLIFETIME if life is greater than
- * TKTLIFEMAXFIXED. The last case, uses the life value (minus
- * TKTLIFEMINFIXED) as an index into the table to extract the lifetime
- * in seconds, which is added to start to produce the end time.
