sorting out difference between aliases and groups in the cases where
unix groups are not explicitly mapped. i.e as a PDC or BDC you can have domain groups, as a member of a domain you cannot. as a member of a domain, unmapped unix groups are assumed to be aliases, and as a PDC or BDC, unmapped unix groups are assumed to be unix groups. there is _one_ other check needed with aliases to be added: unmapped unix groups that have the same name as an NT group on the PDC (for which i will need to write an LsaLookupNames call) should be assumed to be domain groups on the PDC. (This used to be commit 53b49b44e13a4ca9818ebc947372b1374831b568)
