Configuration parameters

• User members of ROLE_ADMIN or ROLE_USER are created into user nodes (these should be the distinguished names CN=ROLE_ADMIN,cn=users,DC=company,DC=com and CN=ROLE_USER,cn=users,DC=company,DC=com).
• Groups can be created on any Active Directory node, because DC=company,DC=com is set as base filter, principal.ldap.role.search.base=DC=company,DC=com.
• All Active Directory groups will be listed, because no filter restriction has been applied principal.ldap.role.search.filter=(objectclass=group).
