Max renewable lifetime issues

Hi all,

I am having a problem in my system which I do not understand why it's
Firstly, I have a KDC running on a RedHat 5.7 machine. I have the parameter
maximum_renewable_life as 5000days in kdc.conf and krb5.conf. For each user
I have added, I also configured as 5000days max_renewable_life.
However, I am experiencing two different situations:

   1. In Linux clients, I only have 1000days as max_renewable_life.
   2. In windows clients (kerberos for windows), I am getting only 30

Does anybody know what is causing this?

Thanks in advance.

Best regards,
