To extend the Active Directory schema with the necessary CIFS-schema extensions

1. Login with Schema Admins privileges on the Active Directory Forest Schema Master domain controller.
2. Download ADCIFSSchema.zip from the Access Appliance server (/opt/VRTSnas/tools/cifs/ADCIFSSchema.zip) with software such as WinSCP.exe.
3. Unzip the file and open each .ldf file to perform a search and replace of the string dc=example,dc=com, replacing the string with the top-level domain component (that is, dc=yourdomain,dc=com) values for the AD forest.
4. Install the schema extensions by executing the schemaupdate.bat file from the command prompt.

To validate the schema extensions

1. Execute regsvr32 schmmgmt.dll in a command prompt window to install the Active Directory Schema Snap-In on the AD server.
2. Enter mmc in Run.
3. On the File menu, click Add/Remove Snapin.
4. In Available snap-ins, click Active Directory Schema, and then click Add.
5. Click OK.
6. Click Attributes in the left frame, and try to find uidNumber and gidNumber in the right frame.

   Validate that the uidNumber and gidNumber attributes have no minimum or maximum value setting by viewing the properties of the attribute objects.

   adding object dc=idmap,dc=example,dc=com
   domain management: quit
   ntdsutil: quit
   Disconnecting from adserver.example.com...

8. Once the application partition has been created, open ADSIedit.msc fromRun, then right-click on ADSI Edit in the left frame, and click connect to ... to connect to the application partition using the settings as indicated:

10. Click Finish to complete the configuration.
11. Once the ou=cifsidmap,dc=idmap,dc=example,dc=com container has been created, right-click the object, and select properties.
