[elenezet]

Hello,

I 'm trying to use misp with CAS OIDC. All seem ok but i have this error :
2023-03-10 13:27:45 Error: [JakubOnderka\JsonException] Could not decode provided JSON
Request URL: /users/login

I try all options but i don't know why there is a problem.
My conf :
misp
nginx for https
oidc

The format is :
{
"sub": "[email protected]",
"service": "https://misptux.com/",
"auth_time": 1678438129,
"attributes": {
"email": "[email protected]",
"roles": "misp-access",
"userId": "E4883"
},
"id": "[email protected]",
"client_id": "sgp5Ngmy345Aq9grDtkywncgz7Hj9HhYhtKorLMSeQoiSXFw9vUMcxU2kSTjTfYk"
}

I don't understant what's wrong?

I believe the "roles" claim is assumed to be an array, so instead of "roles": "misp-access" the Oidc plugin only accepts "roles": ["misp-access"] (I have the same issue with using AWS Cognito which also only supports returning string types in custom claims, so I'm running with a patched plugin to work around this).

[haavardw]

Also it could be that the "roles" claim need to be at the top level, i.e not nested within the attributes block.
