I hadn't noticed that change.

Well, AFAIK it isn't working OOTB properly at least. And that already for 10(+) years. See #3780, #5966, #11778 and the 'OpenID Fix' plugin by Andriy Lesyuk.

I agree. +1. And I think that JPL would wholeheartedly agree too (given the thoughts he expressed at the time in #699#note-14)...

Given this situation, probably very few users are using OpenID login in Redmine. I think it is time to remove OpenID support from Redmine.

If you don't know, then maybe you should ask your users before you do such a change. We just set up a Keycloak for our services and so we wanted to use this. Are you planning to replace it with an alternative? OAuth2?

OpenId was obsoleted by OpenID Connect some years ago and most OpenID providers discontinued their services.

How can a native function get obselete if the alternative is a 3rd party plugin? Should that be a feature or an improvement? That's a huge step backwards.

Also, looking at the pages for issues and pull requests from that OpenID Connect plugin, it looks pretty much unmaintained. So again, how can this be a proper alternative?

Now it is very difficult to find a web service with an OpenID provider service. This means that it is difficult for Redmine users to start using OpenID login.

What? First, there are not only hosted solutions out there. You can set up your own service, see Keycloak or SimpleID. So I don't see how this could be an argument why it should be difficult to start using it. It depends on who you ask. It's very common for companies or organizations to use some sort of SSO or OpenID login, as you maybe know.

And it is not easy for us to test if Redmine's OpenID support is working properly.

As I just mentioned, you can set up your own service. So I don't get why it's not "easy" for you to test if it's working properly. There are definitely possibilities.

Please consider reverting this change or providing an alternative, e.g. login with OAuth2.

Your decision to drop support for OpenID is unbelievable!
I agree with Felix Singer.

hey guys,
you can easily configure keycloak to be an oidc server.
and then use redmine_oidc or relevants. works like a charm!
except you dared using rm5.0. but that's a different story i guess.
cheers,

really ... not funny ... I actually wanted to implement OIDC / OAUTH2

is there a special plugin?

best heiko

While I completely agree with this move (OpenID != OpenID Connect) I think that proper support for OpenID Connect should be provided out of the box and not via a 3rd party plugin.

When we take a look at the network graph of the "most popular" OpenID Connect plugin on GitHub - it's a total mess. Forked several times and no maintainer took over eventually. I'm trying to integrate our Redmine installation with Keycloak right now and are completely unsure, which fork to pick.

Especially since OpenID Connect is becoming more and more popular and this functionality affects the security of a Redmine installation, the current situation is very bleak.
