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
