Remember, this is in the client-side library.  IIRC (and it's been a while
since I looked at it), the change simply makes it so that it won't fail
if there isn't an IP address in the V5 ticket (if there isn't, the client
side library fails without contacting krb524d).  At least, that's what
I remember.
