What version are you running? 1.6.6. What's the URL of the page this enhancement relates to, if any? Authentication setting. Describe the enhancement and the motivation for it. Due to we have multiple Active server in the different branch of our company (yes, my firm do not integrate the AD servers). I would like to know if there is a way to authenticate using multiple server. Currently in our development environment, we had Redmine and Subversion installed, these had supported authenticated via multiple LDAP server, and I would like to find how to do it in the similar way in Reviewboard.
