+Subject: [PATCH] fix nla: don't use server version
+
+FreeRDP currently only supports CredSSP protocol version 3. However the
+current implementation always sent back the version received by the
+server indicating that this version was supported.
+With recent windows updates applied the protocol changed and this approach
+doesn't work anymore (see
+https://msdn.microsoft.com/en-us/library/mt752485.aspx for protocol changes).
+
+With this fix FreeRDP always sends version 3 as supported version.
+
+Credit goes to @mfleisz.
+
+Fixes #4449
+
+(patch above adjusted to apply on top of FreeRDP-2.0.0-rc1)
