I have an existing force.com authenticated site and i am building a community at the moment. I have enabled a profile for both the authenticated site and the community. I can login to both of these separately with the same user. In the community, I have a link to the authenticated site but when the link opens - I am asked to login again even though the user has access to both the community and the authenticated site.
Does anyone know a way to prevent the user from having to login a second time when moving from the community to the authenticated site?
