[keycloak-user] authz client incompatible with client definition

[Denny Israel]

I am writing a command line interface which needs to authenticate against
keycloak. After creating the client definition in keycloaks admin console i
copy the installation data (keycloak.json) into the cli. When i try to use
the authz client i am not even able to create the client because it does
not know the option "ssl-required". When i remove this option the client
can be created but throws another exception when i call
"obtainAccessToken", this time complaining about missing credentials. The
credentials are missing because i made the client "public".
Am i doing something wrong or do i missunderstand the purpose of the authz
client?
