i pioneered apple open director integration with active directory integration while at lower mainland publishing, part of canwest company. later on, I helped global tv to do the same. rest of the canwest, across canada later jumped on it.
back in the days of os x 10.4, it wasn’t as straight forward as it is right now. But even right now i see many people still having challenges setting up single-sign-on and full user/group integration across multiple platforms.
why such integration is important? it allows full integration of mac os x servers with existing microsoft windows based infrastructure, which itself allows for multi platform environment with large enterprises which usually rely on active directory type of user/group management.
