Horray for extensibility!

There are krb5 headers in /usr/include/kerberosV5 on my snv_56 box.

That's hardly specific to Solaris, nor really something Sun can do anything 
about, short of using a different authorization model.  My usual 
recommended answer to this problem is to be less fascist about home 
directory ACL's, but of course that's not for everyone.

Bear in mind that at the moment, we're not talking about whether we should 
accept a grant.  We're talking about whether we should ask for one.  (In 
fact, even that isn't really a topic for openafs-info, but it's too late to 
do anything about that now).
