Is it possible to somehow use dokuwiki to authorize users on the forum, and not vice versa?

Question

DokuWiki

There is a wiki with users.
I would like the user to log in to the wiki and no longer need to log in to the forum, and just logged in through the wiki.
What can I read about this?
In general, is it possible to somehow intercept the session and use it for authorization on the forum or something else?

Answer 1

I'll try to put the question differently.
Can I pull user data from session and what is the easiest way to do it?
Plus, what problems can I run into using this solution?
