Rules for Setting Maximum Ticket Lifetime
Enter a value in the Maximum Ticket Lifetime box to indicate the
maximum lifetime that a ticket may be issued to the principal.
The value format is [Nw] [Nd] [Nh] [Nm], where N is an integer
number, and the lower case suffix identifies the unit of time: weeks, days,
hours or minutes respectively. A number with no suffix, w,d,h or m, is
interpreted as hours.
NOTE Spaces are not allowed between the number and the suffix.
Example
1d3h is one day and three hours
9h18m is nine hours and eighteen minutes
26 is twenty-six hours
You can also express the time units by the full word. For example, 1day is
the same as 1d. Key words are week, day, hour and minute are also
supported.
The maximum lifetime for a ticket issued to any principal in any given
realm is controlled by the settings for the reserved principal
krbtgt/REALM@REALM.
