Hi Jaime
Noticed that you are new on SCN and this is your first post. Welcome to SCN.
Just to share with you that the best way to get an answer is if you provide as much details on your issue. Screenshots (of configuration, logs, etc) are always good. You will have to provide more details on the error/issue you are facing, and what exactly are you referring to when you mentioned "security SOAP envelope".
As you are new here, I'd suggest you read the following blog. I admit it's a long read, but it will go a long way in providing you the right mindset for long term participation in SCN.
Asking Good Questions in the SCN Discussion Spaces will help you get Good Answers
