As far as I know there is not an official plugin yet to support OpenID Connect in NodeBB.
If anyone is still looking for a work-able OpenID Connection option, we've built one for production usage but it should work with any OpenID Connect identity provider.
Supports discovery using the .well-known/openid-configuration URL Supports configurable email claim, defaults to email Supports Logout URL Optionally map roles by a named claim provided in the Userinfo endpoint response Documented option to bypass the default login panelFeel free to open an issue if you find it is missing anything.
