I have two Sharepoint sites. These are accessed by users both internal and external to the company.
The internal users log in to both automatically, the external users have to login any time they want to use either site. The login for both is the same.
Is there any way to ensure that if an external user has logged in to one site, they automatically log in to the other as well? I have some hyperlinks in the sites which link to documents in the other site. These links work fine for internal users but do not work for external users; if they click it they get an error message. If they copy and paste the link and put it in a new browser, it will work; however they will still need to login again even if they have logged in to the first site successfully.
How can I get these hyperlinks to work?
