<(RM) Support tip> SharePoint Integration Configuration tool Permissions Tab
In the RM/CM SharePoint2013IntegrationInstall.pdf it talks about setting up groups and users to populate the fields in this permissions tab.
It is very important that you adhere to those instructions exactly as they are stated.
For example the document viewers and search administrators must be active directory groups with the accounts you want leveraged inside of them, you cannot just configure them as one account
NOTE - You can put a claim in there for ADFS environments.
