File krb5-kvno-230379.patch of Package krb5-mini (Revision c656982d48602dadfbc03d7ce0a0bf0f)

Currently displaying revision c656982d48602dadfbc03d7ce0a0bf0f , Show latest

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.
