The main issues with NIS security (compared with unsigned LDAP
connections) is that passwords my be present in the tables. This isn't
the case with the AD implementation anyway (I think you would need to
use Kerberos authentication, as there are no NIS compatible passwords in
AD, to my knowlege).

In Samba, IDMAP is the plugin interface for assigning the UID/GID
mappings, and can be backed onto many sources, including attributes in
the AD LDAP server (that would be used by the SFU 3.5 NIS server).

I think you should be able to use winbindd, which assists with windows
clients (which expect SIDs), while still maintaining your centralised
mapping. See idmap_ad.
