Meridian supports Active Directory nested groups when the following requirements are met:
- 
                                                    The Meridian application server has been configured as described in Active Directory Security Problems. 
- 
                                                    The domain is in Native mode. For several reasons, Meridian does not support nested groups in Mixed mode. 
- 
                                                    Meridian is configured to browse for domain global groups as described in Configure the BrowseForGlobalGroups Setting. 
- 
                                                    Meridian is configured to browse for nested global groups with the BrowseForNestedGlobalGroups setting described in Windows Registry Keys. 
- 
                                                        Using these settings might have a negative impact on performance. 
- 
                                                        Nested groups are not supported for reserving licenses as described in Reserve Licenses.
