This management agent (MA) moves information about a group from one Microsoft SharePoint Web site to another SharePoint Web site. It uses the IMAExtensibleFileImport interface to import information from an XML file. This MA is used together with a text file that contains the schema that is associated to this information, in Lightweight Directory Access Protocol (LDAP) Data Interchange Format (LDIF) format, which is written to the directory. The Schema Text File for the SharePoint Management Agent section contains a sample text file. This MA also contains the IMAExtensibleCallExport interface. This interface contains methods that you can use to export the information that is obtained from the first SharePoint Web site to another SharePoint Web site.

You must create a Web service that connects to both SharePoint Web sites that are sharing information.

To create the MA

  1. In Microsoft Visual Studio, create a new Visual C# project named SharePointMA.

  2. Add a reference to the Microsoft.MetadirectoryServices namespace.

  3. In a class named Class1.cs, add the code that appears at the end of this procedure.

  4. In Solution Explorer, right-click Web reference, and then select Add Web Reference.

  5. In the dialog box, type the following URL: http://<sharepoint-servername>/_vti_bin/usergroup.asmx

    Set the local reference name to localhost.

  6. In the Class1.cs file that contains the copied source code, add the following using statement to the top of the class.

      Copy Code 
    using SharePointMA.localhost;

  7. Add a Web service to this project that will connect to both SharePoint Web sites.

  8. Add the utilities, as described in Adding Utility Functions for this Management Agent.

Schema Text File for the SharePoint Management Agent

You use a text file to add the schema that is used for this management agent. Create the text file, name it SharePointMA.txt, and copy the following information to that file.

  Copy Code 
iD: iD
email: email
displayName: displayName
isDomainGroup: isDomainGroup
isSiteAdmin: isSiteAdmin
loginName: loginName
notes: notes
objectSid: objectSid
