Instead of replacing NIS I extended it.

I setup a winbind box that did RID mapping from AD and exported those into NIS maps, sans passwords.

I then setup Kerberos on all boxes to authenticate against AD, samba managed the keytab files.

With this I got auto UID/GID generation, my AD users and groups automatically appear and disappear from the NIS maps and I can use those maps for multiple platforms.

Simple, yet effective.
