I have ZCM installed in an AD environment. My user source works ok and actually it finds all my OUs with users. The problem that I am having is when users login in their computers into AD then the adaptive agent prompts them to login again, but they are not able to. Some users in a certain OU do get in with just login in once in AD and automatically login in into ZENWorks, which is the way it suppose to be. I've done everything in my power to make sure it is ok, but I can't figure it out. Any help will be appreciated.
