This will allow group mapping enable if needed via

SilverStripe\SAML\Services\SAMLConfiguration:
  map_user_group: true

and then specify the group claims field

SilverStripe\SAML\Helpers\SAMLUserGroupMapper:
  group_claims_field: 'http://schemas.xmlsoap.org/ws/2005/05/identity/claims/groups'

config() is a static method

Move the query outside the loop, so we are executing one query that fetches everything into Arraylist. then you can look at the titles and check if we have the group or if we need a new one.

$group->write();
}

$member->Groups()->add($group);

I think we also want to remove users from groups they are no longer part of - this probably requires marking groups as 'synced' in some way so we know which ones to remove them from. Its quite likely that a site would have some groups synced with saml but others that are not (we've got at least one project with this requirement) - we wouldn't want to remove users from these 'manual' groups.

Hey @Jianbinzhu, are you still keen to merge this in? There are a few merge conflicts now, but I'd be happy to merge once those are resolved.

I've taken a look at this recently @madmatt - there is another branch that is more up to date, and I'm looking to combine it into some work that's set to come after #68 gets merged ;)
As it stands it's both incomplete & incompatible.
