It should not.

There is a requirement that the pioctl() calls be able to handle the 
larger ktc_token
structure.  However, these calls are local to the client.  As long as 
the client installation
on a given machine is consistent there will be no issues.

What we cannot do is alter the size or structure of the ktc_principal 
since that
structure does need to be transmitted between client and server.

I saw you set the max ticket size to 12000.

It should not.<br>
