Step 7: Create the AD_ECMA2 DLL

Creating and configuring the AD_ECMA2 Extensible Connectivity 2.0 Management Agent for the test lab consists of the following:

  • Create the AD_ECMA2 DLL

Create the AD_ECMA2 DLL

Now we will create our AD_ECMA2 DLL for our AD_ECMA2 management agent. This will be done using the code provided. A full copy of the code is provided in Appendix C: AD_ECMA2 Source Code.

To Create the AD_ECMA2 DLL

  1. Log on to FIM1 as CORP\Administrator.

  2. Click Start, select All Programs, select Microsoft Forefront Identity Manager and double-click Synchronization Service.

  3. In the Synchronization Service, at the top, select Management Agents.

  4. At the top, select Actions, select Create Extension Projects, and choose Extensible Connectivity 2.0 Extension. This will open a Create Extension Project dialog box.

  5. In the Create Extension Project dialog box, next to Programming Language: select Visual C#

  6. In the Create Extension Project dialog box, next to Visual Studio Version: select Visual Studio 2010.

  7. In the Create Extension Project dialog box, next to Project Name: enter AD_ECMA2.

  8. Click OK. This will launch Visual Studio 2010.

    noteNote
    If this is the first time running Visual Studio you will receive a Choose Default Environmental Settings Dialog box. Select General Development Settings and click Start Visual Studio.

  9. On the right, at the top, under the Solutions Explorer, double-click AD_ECMA2. This will open the file with code that has already been written.

  10. In the code, at the top, add using System.Collections.Generic, using System.Collections.ObjectModel, using System.Data.SqlClient and using System.Data. The code should look similar to below:

    
    using System.Collections.Generic;
    using System.Collections.ObjectModel;
    using System.DirectoryServices;
    using Microsoft.MetadirectoryServices;
    using System;
    
    namespace FimSync_Ezma
    
    
  11. In the code, at the top, un-remark the following interfaces: IMAExtensible2CallImport, IMAExtensible2CallExport, IMAExtensible2GetHierarchy, IMAExtensible2GetSchema, IMAExtensible2GetCapabilities, IMAExtensible2GetParameters, and IMAExtensible2GetPartitions. The code should look similar to the code below:

    namespace FimSync_Ezma
    {
        public class EzmaExtension :
        IMAExtensible2CallExport,
        IMAExtensible2CallImport,
            //IMAExtensible2FileImport,
            //IMAExtensible2FileExport,
        IMAExtensible2GetHierarchy,
        IMAExtensible2GetSchema,
        IMAExtensible2GetCapabilities,
        IMAExtensible2GetParameters,
        IMAExtensible2GetPartitions
        {
    
    
  12. Now below our interfaces we will declare some constants that will be used throughout our code. Add the following code:

        IMAExtensible2GetPartitions
        {
    
            private int m_importDefaultPageSize = 12;
            private int m_importMaxPageSize = 50;
            OperationType m_importOperation;
            OperationType m_exportOperation;
            private int m_exportDefaultPageSize = 10;
            private int m_exportMaxPageSize = 20;
            SearchResultCollection results;
            DirectoryEntry dirEntry;
            public string userName;
            public string domain;
            public string dc;
            public string password;
            ADHelper myADHelper;
            public string myADpath;
            public string isSingle;
            public string ADDataType;
            public string myEmpID;
    
    
  13. Now, down below the constructor, add the following code to implement the Management Agents capabilities. This will define what are management agent is capable of.

            public EzmaExtension()
            {
                //
                // TODO: Add constructor logic here
                //
            }
    
            public MACapabilities Capabilities
            {
                get
                {
                    MACapabilities myCapabilities = new MACapabilities();
    
                    myCapabilities.ObjectConfirmation = MAObjectConfirmation.Normal;
                    myCapabilities.ExportType = MAExportType.AttributeReplace;
                    myCapabilities.NoReferenceValuesInFirstExport = true;
                    myCapabilities.FullExport = true;
                    myCapabilities.ConcurrentOperation = true;
                    myCapabilities.ObjectRename = false;
                    myCapabilities.DeleteAddAsReplace = true;
                    myCapabilities.DeltaImport = false;
                    myCapabilities.DistinguishedNameStyle = MADistinguishedNameStyle.Ldap;
                    myCapabilities.NoReferenceValuesInFirstExport = false;
                    myCapabilities.Normalizations = MANormalizations.None;
    
                    return myCapabilities;
                }
            }
    
    
    
  14. Now, below the management agent’s capabilities, add the following method to implement the parameters of our management agent. This will allow us to enter a user name and password to use for connecting to our domain.

    public IList<ConfigParameterDefinition> GetConfigParameters(KeyedCollection<string, ConfigParameter> configParameters,
                                                                ConfigParameterPage page)
            {
                List<ConfigParameterDefinition> configParametersDefinitions = new List<ConfigParameterDefinition>();
    
                switch (page)
                {
                    case ConfigParameterPage.Connectivity:
    
                        configParametersDefinitions.Add(ConfigParameterDefinition.CreateStringParameter("User Name", ""));
                        configParametersDefinitions.Add(ConfigParameterDefinition.CreateEncryptedStringParameter("Password", ""));
                        configParametersDefinitions.Add(ConfigParameterDefinition.CreateStringParameter("Domain", ""));
                        configParametersDefinitions.Add(ConfigParameterDefinition.CreateStringParameter("Domain FQDN", ""));
    
    
    
    
                        break;
    
    
                    case ConfigParameterPage.Global:
    
    
                        break;
    
                    case ConfigParameterPage.Partition:
                        break;
    
                    case ConfigParameterPage.RunStep:
    
                        break;
                }
    
                return configParametersDefinitions;
            }
    
    
  15. Now, below the GetConfigParameter method, add the following code to implement the ValidateConfigParameters method. This is the method where we would configure code to validate the configuration parameters. For purposes of this test lab we don’t validate the parameters but we include this method because it is required to implement IMAExtensible2GetParameters.

    public ParameterValidationResult ValidateConfigParameters(KeyedCollection<string, ConfigParameter> configParameters,
                                                                       ConfigParameterPage page)
            {
    
    
                ParameterValidationResult myResults = new ParameterValidationResult();
    
                return myResults;
    
            }
    
    
  16. Now below the ValidateConfigParameters method, add the following code to implement the GetSchema method. This will be used to discover our schema while the management agent is being setup. The schema discovery in this management agent is limited to just users in AD. It uses the helper class that is created at the end of this section. The code first creates a schematype for a user. Then the code makes a directory entry to the AD schema for the user object and then looks up all of the attributes associated with the user object. Then it determines what type of attribute it is. For example is it a string, a boolean, or an integer. Then it creates the attributes based on this information and adds them to our user schemtype. Finally, it returns the schema.

    public Schema GetSchema(KeyedCollection<string, ConfigParameter> configParameters)
            {
    
    
                userName = configParameters["User Name"].Value;
                password = configParameters["Password"].Value;
                domain = configParameters["Domain"].Value;
                dc = configParameters["Domain FQDN"].Value;
    
    
    
    
                SchemaType userType = SchemaType.Create("user", false);
    
                string DN = (@"CN=User,CN=Schema,CN=Configuration,DC=corp,DC=contoso,DC=com");
    
                dirEntry = new DirectoryEntry(@"LDAP://" + dc + @"/" + DN, userName, password);
                myADHelper = new ADHelper();
                #region ForLoop
                List<string> myAttributeList = new List<string>();
    
                foreach (var prop in dirEntry.Properties.PropertyNames)
                {
    
    
                    #region MayContain
                    //Loop threw the values in mayContain
    
                    if (prop.ToString() == "mayContain")
                    {
    
                        List<string> mayContain = myADHelper.GetMayContain(dirEntry, prop.ToString());
    
                        foreach (string s in mayContain)
                        {
                            if (myAttributeList.Contains(s))

                            {
                                myAttributeList.Add(s);
                            }
                        }

  19. Now, below the GetPartitions method add the following code to implement the OpenImportConnectionResults method. This will initialize our connection information with Active Directory.

      public OpenImportConnectionResults OpenImportConnection(

                {
    
                    foreach (SearchResult myResult in results)
                    {
    
    
                        string myDN = myResult.Properties["distinguishedName"][0].ToString();
                        string myLastName = myResult.Properties["sn"][0].ToString();
                        string myEmpID = myResult.Properties["employeeID"][0].ToString();
                        string mySamAcct = myResult.Properties["sAMAccountName"][0].ToString();

                        string myFullName = myResult.Properties["displayName"][0].ToString();
                        CSEntryChange csentry1 = CSEntryChange.Create();
    
                        csentry1.ObjectModificationType = ObjectModificationType.Add;
                        csentry1.ObjectType = "user";
                        csentry1.DN = myDN;
    
                        
                        csentry1.AttributeChanges.Add(AttributeChange.CreateAttributeAdd("givenName", myFirstName));
                        csentry1.AttributeChanges.Add(AttributeChange.CreateAttributeAdd("mail", myMail));
                        csentry1.AttributeChanges.Add(AttributeChange.CreateAttributeAdd("sn", myLastName));
                        csentry1.AttributeChanges.Add(AttributeChange.CreateAttributeAdd("sAMAccountName", mySamAcct));

                        csentries.Add(csentry1);
                    }
                }
    
                if (OperationType.Delta == m_importOperation)
                {
                }
    
    
    
    
    
                // Create the result
                importReturnInfo = new GetImportEntriesResults();
                importReturnInfo.MoreToImport = false;
                importReturnInfo.CSEntries = csentries;
    
           
                return importReturnInfo;
            }
    
    
    
  21. Now, below GetImportEntriesResults add the following code to implement CloseImportConnectionResults. This will close our connection.

    public CloseImportConnectionResults CloseImportConnection(CloseImportConnectionRunStep importRunStepInfo)
            {
    
                return new CloseImportConnectionResults();
            }
    
    
  22. Now, below CloseImportConnectionResults add the following code to implement ImportMaxPageSize and ImportDefaultPageSize.

        public int ImportMaxPageSize
            {
                get
                {
                    return m_importMaxPageSize;
                }
            }
    
            public int ImportDefaultPageSize
            {
                get
                {
                    return m_importDefaultPageSize;
                }
            }
    
    
  23. Below the ImportDefaultPageSize add the following code to implement the OpenExportConnection method. This method will initialize our connection for exports.

    public void OpenExportConnection(KeyedCollection<string, ConfigParameter> configParameters,
                                  Schema types,
                                  OpenExportConnectionRunStep exportRunStep)
            {
                string DN = (@"OU=ECMA2,DC=corp,DC=contoso,DC=com");
                userName = configParameters["User Name"].Value;
                password = configParameters["Password"].Value;
                dc = configParameters["Domain FQDN"].Value;
                dirEntry = new DirectoryEntry(@"LDAP://" + dc + @"/" + DN, userName, password);
    
            }
    
    
  24. Now, below OpenExportConnection and the following code to implement PutExportEntriesResults. This is the workhorse of a call-based MA with regard to exporting. This method is responsible for writing our information to AD. This method is responsible for writing our information to AD. This is done by taking the csentries that are passed in by the Synchronization Service and depending on the type of modification, whether it is object or attribute, a corresponding LDAP command is built and then executed on AD.
