Subject: [PATCH 3/3] krb5: fix entry order in MEMORY keytab
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since krb5_kt_add_entry() adds new entries at the beginning of a MEMORY
type keytab and not at the end a simple copy into a MEMORY type keytab
will revert the order of the keytab entries. Since e.g. the sssd_krb5
man page give hints about where to add entries into keytab files to help
SSSD to find a right entry we have to keep the order when coping a
keytab into a MEMORY type keytab. This patch fixes this by doing a
second copy to retain the original order.
