红帽全球峰会14.5. Configuring the global ticket lifecycle policy
The global ticket policy applies to all service tickets and to users that do not have any per-user ticket policies defined.
The following procedure describes adjusting the maximum ticket lifetime and maximum ticket renewal age for the global Kerberos ticket policy using the ipa krbtpolicy-mod command.
While using the ipa krbtpolicy-mod command, specify at least one of the following arguments:
-
--maxlifefor the maximum ticket lifetime in seconds -
--maxrenewfor the maximum renewable age in seconds
Procedure
To modify the global ticket policy:
[root@server ~]# ipa krbtpolicy-mod --maxlife=$((8*60*60)) --maxrenew=$((24*60*60)) Max life: 28800 Max renew: 86400In this example, the maximum lifetime is set to eight hours (8 * 60 minutes * 60 seconds) and the maximum renewal age is set to one day (24 * 60 minutes * 60 seconds).
Optional: To reset the global Kerberos ticket policy to the default installation values:
[root@server ~]# ipa krbtpolicy-reset Max life: 86400 Max renew: 604800
Verification
Display the global ticket policy:
[root@server ~]# ipa krbtpolicy-show Max life: 28800 Max renew: 86640
