Hi,

I am having problems to get TGTs with renewal periods as specified in
kinit -r option. My kdc.conf realm stanza has these two paramters set:

            max_life = 10h 0m 0s
            max_renewable_life = 7d 0h 0m 0s

I have explicitely set forwadable flag in the realms
default_principal_flags parameter
I have played with various values in /etc/krb5.conf [libdefault] stanza
renew_lifetime,and ticket_lifetime values, and I have set the principal
-maxrenewlife to 7 days. Still whenever I do a kinit -l 10h -r 7d my
renew untill timestamp is the same as the ticket creation one:

stefano@filo2 ~ $ klist -fc
Ticket cache: FILE:/tmp/krb5cc_1000
Default principal: stefano@SANTORO.ORG

Valid starting     Expires            Service principal
10/15/05 03:51:29  10/15/05 13:51:29  krbtgt/SANTORO.ORG@SANTORO.ORG
        renew until 10/15/05 03:51:29, Flags: RI

I would really appreciate any insights to solve this riddle.

Ciao
Stefano
