Issue with Role Mapping in Grafana OAuth Configuration with Keycloak

Grafana Authentication
, , ,
1

Hello,

I am currently working on setting up OAuth in Grafana (version 9.5.2) using Keycloak as the OAuth provider. While I’ve managed to get the OAuth connection functioning correctly, I am encountering an issue with role mappings that I’m hoping someone might be able to assist with.

To develop, Grafana does not seem to correctly map the roles defined in Keycloak. The roles sent from Keycloak appear to be ignored or misinterpreted by Grafana.

To assist with troubleshooting, here is a snippet of the Grafana debug logs during a login attempt:

As you can see, the ID token (in JSON format) sent by Keycloak clearly includes the correct roles.

"resource_access": {
    ...
    "grafana-oauth": {
        "roles": [
            "editor",
            "admin",
            "grafanaadmin"
        ]
    },
    ...
}

The path seems to be : resource_access.grafana-oauth.roles

Here is my Grafana OAuth configuration:

[log]
level=debug

[server]
root_url=https://grafana.xxxxxx.xx

[auth.generic_oauth]
enabled = true
name = xxxxxx
allow_sign_up = true
client_id = grafana-oauth
client_secret = xxxxxx
scopes = openid email profile offline_access roles
email_attribute_path = email
login_attribute_path = username
name_attribute_path = full_name
auth_url = https://sso.xxxxxx.xx/realms/xxxxxx/protocol/openid-connect/auth
token_url = https://sso.xxxxxx.xx/realms/xxxxxx/protocol/openid-connect/token
api_url = https://sso.xxxxxx.xx/realms/xxxxxx/protocol/openid-connect/userinfo
allow_assign_grafana_admin = true
role_attribute_strict = true
role_attribute_path = contains(resource_access.grafana-oauth.roles[*], 'admin') && 'Admin' || contains(resource_access.grafana-oauth.roles[*], 'editor') && 'Editor' || 'Viewer'

I also tried with some variants like :

role_attribute_path = contains(roles[*], 'grafanaadmin') && 'GrafanaAdmin' || contains(roles[*], 'admin') && 'Admin' || contains(roles[*], 'editor') && 'Editor' || 'Viewer'

I’ve gone through Grafana and Keycloak’s documentation to try and resolve this but to no avail. I would greatly appreciate any insights or suggestions you might have on this matter.

Thank you in advance for your assistance.

Thanks a lot, It was exactly that ! My bad…

So it works perfectly with :
role_attribute_path = contains(resource_access."grafana-oauth".roles[*], 'admin') && 'Admin' || contains(resource_access."grafana-oauth".roles[*], 'editor') && 'Editor' || 'Viewer'
