[keycloak-user] Keycloak OpenIDConnect bearer token problem

[NAPPERT Olivier]

Hello,

I am trying to use Keycloak v3.2 standalone (Final) as an OpenID Connect Identity Provider, with an instance of LemonLDAP::NG working as my OIDC Relying Party. The latter is already configured and works well with multiple OIDC Identity Providers, like Google or other LL::NG instances.

When accessing the Keycloak token endpoint, the authentication fails with the following message :


Token type is bearer but must be Bearer
[perl:debug] CGI.pm(114): /usr/share/perl5/Lemonldap/NG/Portal/AuthOpenIDConnect.pm 133:
[perl:error] Token response is not valid


Do you know how to change the token type sent in the Keycloak configuration please ? From my understanding the OpenID Connect standard states that the Token type MUST be Bearer, so I suspect that I'm not the first who's had this problem.

Best regards,

Olivier NAPPERT
