The company I work for was purchased some time ago, and we have been gradually migrating into their systems. The next step will be to move completely into their domain. Our current EPDM vault uses windows authentication through active directory. We have set up a user group in our AD for vault users, so once the user is in that group they can be added to the vault. My question is what happens when we are moved into the new domain, and have been assimilated into their AD. What can I expect to break, and how do I fix it? All help is appreciated.
