+Subject: [PATCH] Fix build failure against samba 4.12.0rc1
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The ndr_pull_get_switch() function was dropped, but it was just a wrapper
+around the ndr_token_peek() function, so we can use this approach on both
+old and new versions of libndr.
