I’m trying to configure a self-hosted Docker instance of Discourse to authenticate users with SAML, using Okta as the IdP. At first my setup looked identical to what @runofthemill posted here: Discourse-saml + Okta endless redirect. But then, thanks @skoota, I re-set all the native SSO configs to the defaults, since I understand want to be relying just on the plugin.
So now plugin is successfully installed, and SAML appears as a login option, but I get this error when I try to use it:
I took a look at the library this error seems to orginate from, and it’s not obvious to me what’s going wrong. But I’m not a rubyist, so maybe (hopefully!) I’m missing something obvious.
Suggestions? Thanks in advance.
