From 881e3b47a17d7d0b3687ef26d782fc3281a8faa3 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/7] s3:libads: prefer ENCTYPE_AES256_CTS_HMAC_SHA1_96 in
ads_keytab_add_entry()
This is currently not critical as we only use keytabs
only as acceptor, but in future we'll also use them
for kinit() and there we should prefer the newest type.

Subject: [PATCH] s3:lib:tls: Use better priority lists for modern GnuTLS
We should use the default priority list. That is a good practice,
because TLS protocol hardening and phasing out of legacy algorithms,
is easier to co-ordinate when happens at a single place. See crypto
policies of Fedora.
