How to pass options to the Guzzle Client?

[mdevlamynck]

I fail to understand how to use the options configuration of this bundle. The Configuration defines it as an array of scalars and (if I'm not mistaken) the Guzzle Client expects an associative array of the form ['config key' => 'value'].

So it seems I need to use it like so :

p_rayno_cas_auth:
    …
    options:
        some_option_1: "some_value_1"
        some_option_2: "some_value_2"

When the bundle's config only accepts

p_rayno_cas_auth:
    …
    options:
        - "some_scalar_1"
        - "some_scalar_2"

Am I missing something?
