Hello,
There is (limited) information in the integrated helpfiles of SP (section Security Addins).
- The SSC options are available if there are "registered" SP users (create/import users throught the Accounts menu);
- Tje ASP.net Security Context is (technically) more complex and challenging (check the site links in the helpfiles) but can be used when SP is integrated with the ASP security model.
Hope this information will be usefull.
