Virtual server object is missing nfap attributes

The nfap attributes are missing from the virtual server object. To resolve:

1.   Login to iManager
2.   Schema -> Object Extensions
3.   Browse to, and select your virtual server object
4.   Click the Add button
5.   Add the following:
      nfapCIFSConfigInfo
      nfapCIFSDomainProperties
      nfapLoginProperties
6.   Click Close
7.   Select: Directory Administration -> Modify Object
8.   Browse to, and select your virtual server object
9.   Choose the "Other" menu below the "General" tab
10. Move the following attributes from the "Unvalued" column to the "Valued" column:
      nfap:CIFSServerName
      nfap:CIFSAttach
         ****** Please Note ******
          As you move these attributes over, you will be required to fill in a value for each.  The   
          CIFSServerName will be the Name you would like to give the CIFS server for name
          resolution.  The CIFSAttach should be the IP address of the resource you are CIFS enabling.
11.  Offline / Online the Resource

Note:

If you fail on step 5 to see the nfap attributes, the schema may not be extended for cifs.  To extend the schema, simply perform:

ndssch <adminuser.container> /opt/novell/cifs/schema/nfap.sch

If /opt/novell/cifs/schema/nfap.sch does not exist, there is a good chance that cifs is not installed on this server.  Install cifs and try again.
