Previously is was possible to access Confluence by using an url with an os_username and an os_password. Recently we moved Confluence to an other environment with a more recent version (from 5.10.8 to 7.2.2) in the new environment the url including os_username and os_password is not working anymore.
Is this because of the newer version or do I need to configure something in Confluence?
What possibilities are there in Confluence to do this? What we want to do is share readonly Confluence spaces with some of our development partners and we want to avoid they all need their own login credentials.
