Hi, I need to install a wiki, and i'm thinking on mediawiki, but i have a requirement, that all users don't need to register again in this wiki, but they sould use a my mailserver with they accounts that already use. Is it possible to mediawiki login users in suche way? I just need that media wiki to do ssh to my mailserver and confirm it is a trusted user. And as a plus if user don't exist in mediawiki DB add it to the wiki users DB? Or in other way there is a way to change login module of media wiki? Can anyone help me?
