Ticket renewal not working

[Tiago Elvas]

Hi there,

I am experience problems at the time of ticket renewal.
For this test I am using 5minute tickets (for quick testing) and so:

# /var/kerberos/krb5kdc/kdc.conf
max_life = 5m 0s
max_renewable_life = 5m 0s
# /etc/krb5.conf
ticket_lifetime = 5m
renew_lifetime = 5m

The principal in use is named "opends".

I log in and this is my ticket:

[opends ~]$ klist -f
> Ticket cache: FILE:/tmp/krb5cc_505
> Default principal: opends at DOMAIN.COM
> Valid starting     Expires            Service principal
> 07/18/12 18:01:33  07/18/12 18:06:33  krbtgt/DOMAIN.COM at DOMAIN.COM
>         renew until 07/18/12 18:06:33, Flags: FPRIA
>
> Kerberos 4 ticket cache: /tmp/tkt505
> klist: You have no tickets cached


I then do "kinit -R",

[opends ~]$ kinit -R
> [opends ~]$ echo $?
> 0
> [opends ~]$
> [opends@ ~]$ klist -f
> Ticket cache: FILE:/tmp/krb5cc_505
> Default principal: opends at DOMAIN.COM

Valid starting     Expires            Service principal
> 07/18/12 18:02:25  07/18/12 18:06:33  krbtgt/DOMAIN.COM at DOMAIN.COM

        renew until 07/18/12 18:06:33, Flags: FPRIAT
>
> Kerberos 4 ticket cache: /tmp/tkt505
> klist: You have no tickets cached



Does anybody know why this is happening?
The system is intended to be used along several and "random" days and I
should not get a ticket expired error so it should be automatic (like in a
cronjob doing this kinit -R)

Thanks in advance.

Best regards,
Tiago
