Kerberos ticket policy

There is a single Kerberos ticket policy. This policy defines the
maximum ticket lifetime and the maximum renewal age, the period during
which the ticket is renewable.

You can also create a per-user ticket policy by specifying the user login.

For changes to the global policy to take effect, restarting the KDC service
is required, which can be achieved using:

service krb5kdc restart

Changes to per-user policies take effect immediately for newly requested
tickets (e.g. when the user next runs kinit).

EXAMPLES:

 Display the current Kerberos ticket policy:
  ipa krbtpolicy-show

 Reset the policy to the default:
  ipa krbtpolicy-reset

 Modify the policy to 8 hours max life, 1-day max renewal:
  ipa krbtpolicy-mod --maxlife=28800 --maxrenew=86400

 Display effective Kerberos ticket policy for user 'admin':
  ipa krbtpolicy-show admin

 Reset per-user policy for user 'admin':
  ipa krbtpolicy-reset admin

 Modify per-user policy for user 'admin':
  ipa krbtpolicy-mod admin --maxlife=3600
