Hello, I would like to authenticate the users of my installation of Discourse with our University SAML. I’m using the docker version of Discourse with the SAML plugin. I’ve tried to follow the instructions on the GitHub site of this plugin. Everything works fine until I see the following form: […

Hello Ronald :slight_smile: :wave: really glad to see more and more Universities joining the Discourse family :smiley: You have quite an interesting issue! My SAML/SSO fu isn’t strong so I am not sure what is happening here, but can you try enabling the verbose sso logging site setting? It would he…

My guess (and my experience with saml is limited, I think I’ve only once helped someone configure it) is that the issue is on the saml side. It’s either configured to send the hash or you’re somehow using the wrong field.

After more research I found that the ‘hashed’ code in the registration form is actually the NameID send by the IdP. In the configuration of SAML on the IdP I’ve also enabled the following attributes: Display Name: urn:mace:dir:attribute-def:displayName Full Name: urn:mace:dir:attribute-def:cn Emai…

Hello @ronligt , any success in mapping the right attributes via discourse-saml configs? I’ve been trying using this config in the plug-in but no lucky so far: [Screenshot 2023-05-03 at 08.27.45] Have a good one! :slight_smile:
