+Subject: [PATCH] nss: Collision with external nss symbol
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+One of our internal static function names started
+to collide with external nss symbol. Additional
+sss_ suffix was added to avoid the collision.
+
+This is needed to unblock Fedora Rawhide's
+SSSD build.
