user-attributes not working well

[mwagner]

Hi,

I'm trying to pass some user-attributes, but seems to fail. I want to add the attribute 'name' and 'is_admin':

:user-attributes="['name' => 'Admin User', 'is_admin' => true]"

In this case both attributes are ignored by the package. If I only pass 'is_admin' => true then it works. Doesn't this object allow for multiple attributes?
