That's one things to add schema in your AD, that's another thing to use
that schema.

Adding schema for rfc2307 in AD grant you possibility to set uidNumber,
gidNumber, loginShell and others attributes to your AD users. That grant
you that possibility but you are free to use that possibility.

Next step is to define xidNumber to your users.
