Clicking the View Default Security Owners button from the Role Members screen opens this screen. This is useful information when you want to remove a role, and need to understand where it is being applied before removing it.
This screen lists all folders which have this role applied on their default security policy. This includes internal system folders. Internal system folders hold the default security policies for different types of accounts, such as Independent, MOM, MCM and CSR accounts. The only way to change Default Security Policy on these folders is to manually modify the SecurityPolicies.xml file and re-synchronize the system (you do this in the MetraTech Platform Manager application).
