Domino 8.5.1 introduces two options for SPNEGO based integration with Active Directory. For this to work, certain information needs to be copied between AD or Domino, depending on your choice of architecture. For both these choices there's a TDI solution that gets the work done.
Please read about the two options in the attached presentation (odp format)
Then take a quick look at the video that shows you a little about TDI7 in general
This presentation describes what the TDI solution does, and then walks through a little more TDI terminology and capability
At this stage you're ready to read the specific documentation of the solution that you will deploy
Finally grab the attached .zip file that contains the TDI solution (v1.7) and get going!
Notes:
This solution can be run as often as you'd like. It will not create duplicates or add values where attributes already contain the correct information
TDI can also perform change detection on the source. We will update this solution with that capability in the near future. This is pretty simple for a person slightly familiar with TDI, so it's an excellent exercise for the reader.
