Question about sso Redmine?

Question

Redmine

Good day dear!
The question is, is there a site that needs to be linked with a button so that it can go directly to the section in Redmine without authorization (authorization should take place automatically without entering any data). Can you please tell me if something can be done? I read on the Internet, they say through cookies, but I would like to see a more detailed version.
Thank you for your assistance!

Answer 1

What are we talking about domain authentication through LDAP, ActiveRecord, or just two separate services (redmine and some site running on another hosting)? If the first, that is, the free Single auth solution , you can read about its configuration here https://habrahabr.ru/post/245661/. If the latter, then we are talking about the implementation of a full-fledged SSO service, articles on the topic of how such services are arranged in a shaft, but you are unlikely to find a ready-made solution for redmine.
