Username not found

[mmortier-pf]

Hello guys,

I'm trying to implement the library in my Symfony project (v 2.8) but I'm facing an issue.

It seems like the property username is not mapped.

I tried to inject the attributes but it doesn't work. If I log the attributes parameter, I receive the right data.

public function setSamlAttributes(array $attributes)
    {
        $this->email = $attributes['Email'][0];
        $this->username = $attributes['Firstname'][0];
    }

If you need, here is more informations:
