Try this as a replacement body text.

You have just logged out of the single sign-on (SSO) website, however, you may still be logged into other sites that use SSO. You can see a [[list of sites]] that you have logged into from your account page.

[[list of sites]] should link to their account page so they can view the list. I think the message makes it clear they've logged out and that it follows logically that they'll have to log back in to see the list.
