+Subject: Clean our state
+
+Make sure our state is clean when we're at the login window. This
+code, adapted from upstream's development branch, ensures settings
+from previous connections are cleared.

+Subject: Fix account validation with glibc crypt
+
+Starting with glibc 2.17, crypt() can return NULL which can cause
+xrdp-sesman to segfault. This patch backports upstream's fix for
+this as well as changes auth_userpass so it can validate SHA-256
+and SHA-512 hashed passwords.
