Well I asked SAP to make note 1852377 available to customers and the response from SAP support was
"I received permission to have the article deleted from our system
we will no longer give customers configurations for unsupported 3rd
parties..." 
So amazingly SAP will delete the note that helped me. SAP wont support NW as a web server for BOE in a SSO environment 
but will I guess help with BOE tomcat and SSO. 
So we have decided to shutdown our NW Portal for BOE and revert to tomcat.
