I'm running with:

[appdefaults]
	renewable = true
[libdefaults]
	renew_lifetime = 7d

on my Solaris clients and it seems to do the right thing (against a  
Heimdal kdc).  Looking at the Solaris 9 krb5.conf man page I see  
max_renewable_life as an [appdefaults] option, but nothing else.   
Perhaps the renew_lifetime line isn't needed?

I suspect the renew_lifetime line is a carryover from some other  
krb5.conf.  In Heimdal it can go in either section and "7d" is OK (vice  
7days).

An MIT 1.3 man page does not mention max_renewable_life, and puts  
renew_lifetime in [libdefaults] only.

I suppose I shouldn't complain.  Everyone really is pretty compatible  
if you're willing to deal with the details.  That indicates serious  
effort on the part of all the implementors, free and commercial alike.
