In Symantec Reporter 9.x and 10.x, you can integrate Reporter with an LDAP server, which allows you to configure RBAC (Role Based Access Controls) policies.
To perform user and group based authentication and authorization, you must configure the user and group base DN.
To find the user and group base DN, run a query from any member server on your Windows domain.
dsquery user -name <known username>
dsquery group -name <known group name>.
See Finding your base DN in Active Directory for more information about what Microsoft tools are available.
