AD Integration and Default MP
This is something that I can not remember seeing being documented. When you do AD Integration it puts the information into the Default MP. There is no option of where to save the data when you are doing the AD Integration wizard. I assumed that it went into the SQL database but I have found all the info embedded in the Default MP.
This makes it more important to keep all other overrides and changes in a separate MP as you do not want to have to delete the Default MP if you need to delete another MP and there is an overrode in it which will then create a dependency to the MP you are trying to delete.
Relevant to OpsMgr SP1. Other versions may differ.
