This won't do what you think.  First, we're not parsing 
"ticket_lifetime", despite having some indications around that we do.  
Second, the time-interval parsing code requires a unit.  (I think both 
of these will change in the 1.4 release.)

Try "700s" or "700m".

Also check the properties on the client and service principals 
(including the krbtgt principals).  I forget whether max renewable 
lifetime is one of them, but if it is, it would be set when the 
principal is created or when you use "modprinc" in kadmin, and the 
config file specifications won't extend it, only (potentially) further 
limit it.
