User attribute mapping

[dmyers]

I've been working to integrate this package and was thinking it would be nice if it supported like a config of mapping of urn:oid values to model attributes automatically which then can be used on the model such as this:

$attributes = $samlUser->mappedAttributes();
$laravelUser->fill($attributes);

The config could look something like this:

return [
        'first_name' => [
            'urn:oid:2.5.4.42',
            'firstName',
        ],
];

And the Saml2User method:

    protected function mappedAttributes(): array
    {
       $attributes = $this->getAttributes();
        $result = collect(config('saml2.attribute_mapping')
            ->mapWithKeys(function ($map, $attribute) use ($attributes) {
                foreach ($map as $key) {
                    $values = Arr::get($attributes, $key);
                    if (empty($values) || !is_array($values)) continue;
                    $value = Arr::first($values);
                    if (empty($value)) continue;
                    return [$attribute => $value];
                }
                return [$attribute => null];
            });
        }

        return $result->all();
    }

Good idea!

I think most applications will require extra user attributes & claims (See AAD example https://learn.microsoft.com/en-us/answers/questions/248748/cant39-find-the-34user-attributes-amp-claims34-sec.html#answer-248989), but this package doesnt provide a solution for this.

The alternative is to store this information in another table (The package currently doesnt support using the saml2_tenants.metadata column because the : symbol isnt allowed with their ConsoleHelper::stringToArray encoder/ decoder).

Would you be open to a pull request to add another column to the saml2_tenants table for this, which stores a json column. @dmyers I could get it started, or if you have a solution already we can start from there.

Hello, did you succeed in getting custom attributes? I added custom attributes in my AD "Attributes and Claims", but I can't see them in the ->getAttributes().
