Why put user-dn in the attribute-map if it will never be coming from
the IdP (i.e., there's nothing to map it from)? Try removing that.

Here's the example from the documentation:

  <Template>$givenName $sn</Template>

So I'd lose all the double quotes and spurious whitespace, like:

  <Template>id=$user-unique,ou=people</Template>
