File krb5-kvno-230379.patch of Package krb5-mini.34946
From patch attached to http://krbdev.mit.edu/rt/Ticket/Display.html?id=3349, at http://krbdev.mit.edu/rt/Ticket/Attachment/23851/13214/kvno.diff, adjusted as needed to apply to 1.10. FIXME: I'd like to better handle cases where we have a new key with the right version stored later in the keytab file. Currently, we're setting up to overlook that possibility. Note that this only affects the path taken when krb5_rd_rep() is passed a server principal name, as without a server principal name it already tries all of the keys it finds in the keytab, regardless of version numbers.
