From f722b0743811a4a5caf5288fa901cc8f683b9ffd Mon Sep 17 00:00:00 2001
From: Andrew Bartlett <abartlet@samba.org>
Date: Wed, 8 Nov 2006 01:48:35 +0000
Subject: r19633: Merge to lorikeet-heimdal, removing
 krb5_rd_req_return_keyblock in favour of a more tasteful replacement.

Remove kerberos_verify.c, as we don't need that code any more.
Replace with code for using the new krb5_rd_req_ctx() borrowed from
Heimdal's accecpt_sec_context.c
