<xs:element name="ReplicaDirectoryServer" nillable="true" type="sera:ArrayOfstring" />
The ReplicaDirectoryServer element is populated from the server!dnsHostName attribute on the parent object of all nTDSDSA objects ([MS-ADTS] section 184.108.40.206.220.127.116.11.1) that meet the following criteria:
The objectClass attribute of the object is nTDSSDA and the client has access rights to read the attribute.
The nTDSDSA!msDS-hasDomainNCs attribute is equal to the rootDSE!defaultNamingContext attribute ([MS-ADTS] section 18.104.22.168.2.3) and the client has access rights to read the attributes.
The nTDSDSA!objectCategory attribute ([MS-ADTS] section 22.214.171.124.6) refers to the classSchema object for the nTDSDS class and the client has access rights to read the attribute.
The server!dnsHostName attribute is present on the parent of the nTDSDSA object and the client has access rights to read the attribute.
If no nTDSDSA objects satisfy the above requirements, the server returns a null ActiveDirectoryPartition/ReplicaDirectoryServer element.
