Credentials for Redfish API for Asrock Rack IPMI

I have the Mainboard WC621D8A-2T.
I am able to login into the IPMI Web Interface.
Now I would like to use the Redfish API, but I am not able to authenticate.
If I understand the API Spec correct, A POST to

https://192.168.168.149/redfish/v1/SessionService/Sessions

With payload:

{
  "UserName":"user", 
  "Password":"password"
}

To receive a Session Token.

But that does not seem to work. Is there any other configuration required?

The default credentials ( Administrator / superuser)
