Post From: SC1809 DTC-Server sends one or more SecurityDefinitionResponse right after login

I am working on a c# client for the DTC Server.

I noticed that right after successfull login the server sends some SecurityDefinitionResponses without having them requested.
Seems it depends how many chart symbols are open on the SC-Instance it could be much more.

Of course i can simply dismiss those messages but wondering whether this is the desired behaviour.
Encoding is binary connect to the standard port
