Integrating current 10.4.11 OD environment with AD

Please forgive me if something like this has been posted before… I’m a newbie to this site

I recently became the Macintosh system administrator for a company. They currently have an OD master setup with one or two OD replicas. There are about 100 users in OD currently that mainly just have access to file shares. There are only a few machines actually bound to OD with users authenticating against it to login.

Recently some changes have been made to the infrastructure of that company… now they want to be able to have the same user account information and credentials between AD and OD. The only way I am aware of to do this right is to setup the “golden triangle”. With having an existing OD environment, how do you suggest I attack this without breaking something? Do I have to demote the OD Master to a stand-alone server before the bind to AD? To be very careful I plan on probably creating a bootable image of the server boot disk before attempting anything. I also want to make sure this doesn’t break any of thier other services or backup system.

Thank you,
Ken
