Can anyone please tell me, what is the difference between active directory federation services (ADFS) and single sign-on (SSO)?
From a simple look at things both seem to do much the same thing in identity management, making it so users require only a single logon to access many services. My company of course currently uses AD but there is talk of getting a SSO service. I'm not quite understanding the difference other than SSO will also stretch to web apps.
What are the key basic differences?
I tried asking this on SO but didn't even get a good reason as to why people can't answer it. I would really appreciate some pointers. I mainly deal with the hardware side of things, and I'm fairly new to the game, so its all rather mysterious to me.
