Custom Attributes in Authentik OIDC (lemmy.ca)

I'm trying to setup owncloud with single sign on using Authentik. I have it working for normal users. There is a feature that allows automatic role assignment to users so that admin users from authentik become admin users for owncloud.

This is described here: https://doc.owncloud.com/ocis/next/deployment/services/s-list/proxy.html#automatic-role-assignments.

In this document, they describe having attributes like

- role_name: admin
  claim_value: ocisAdmin

The problem I have is I don't know how to input this information into an Authentik user. As a result, owncloud is giving me this error:

ERR Error mapping role names to role ids error="no roles in user claims" line=github.com/owncloud/ocis/v2/services/proxy/pkg/userroles/oidcroles.go:84 request-id=5a6d0e69-ad1b-4479-b2d9-30d4b4afb8f2 service=proxy userid=05b283cd-606c-424f-ae67-5d0016f2152c

Any authentik experts out there?

I tried putting this under the attributes section of the user profile in authentik:

role_name: admin
claim_value: ocisAdmin

It doesn't work and it won't let me format YAML like the documentation where the claim_value is a child of the role_name.

not an authentik user, but after skimming their docs i think you have to:

  1. create a role "ocisAdmin" via authentiks admin interface
  2. give this role to a group in the admin interface or create one.
  3. assign a user thats supposed to be an owncloud admin to the group

it might be that you also have to define somekind of mapper to include this in the informations owncloud receives from authentik, but as i said i only skimmed the docs and would personally just try it without the mapper.

tried this and also tried making a role in authentik assigned to the group called ocisAdmin and added the admin user to it, it still gives the same error. Seems like I need to define a proxy.yaml file in owncloud with the roles, I did this and it still doesn't work.

does authentik offer an option to preview a jwt for a given user? might be as simple as that the claim is not named "ocisAdmin" or is not a toplevel entry in the jwt.
