How to: Use ACS Management Service to Configure Rules and Rule Groups

Launch the ACS Management Portal. For more information about how to launch the ACS Management Portal, see ACS Management Portal.

Get the value of the ACS management service account. You can use the default ManagementClient account. To view this value, in the ACS Management Portal, click Management service under the Administration section in the tree on the left-hand side of the page.

Get the value of the ACS Management Service account password. To view this value, do the following:

1. In the ACS Management Portal, click Management service under the Administration section in the tree on the left-hand side of the page.
   
   
2. On the Management Service page, click ManagementClient under Management Service Accounts.
   
   
3. On the Edit Management Service Account page, under Credentials, click Password.
   
   
4. On the Edit Management Credential page, copy the value in the Password field.
   
   

Get the name of your Windows Azure namespace from the Windows Azure portal or from the URL of your ACS Management Portal. For example, in http://contoso.accesscontrol.windows.net, the name is contoso.

Get the ACS hostname. Usually, it is accesscontrol.windows.net.

Open Visual Studio 2012 and create a new console application project under the Windows installed template.

Add the following code to the Program class and then assign serviceIdentityPasswordForManagement, serviceNamespace, and acsHostName variables to the appropriate configuration information that you collected in the previous step.

public const string serviceIdentityUsernameForManagement = "ManagementClient";
public const string serviceIdentityPasswordForManagement = "My Password/Key for ManagementClient";
public const string serviceNamespace = "MyNameSpaceNoDots";
public const string acsHostName = "accesscontrol.windows.net";
public const string acsManagementServicesRelativeUrl = "v2/mgmt/service/";
static string cachedSwtToken;

Right-click References, click Add Reference, and add a reference to System.Web.Extensions.

Note
You might have to right-click your sample console application name in the Solution Explorer, select Properties, and change the target framework of your sample application from .NET Framework 4 Client Profile (assigned by default when you create a new console application) to .NET Framework 4.

Right-click Service References, click Add Service Reference, and add a service reference to the Management Service. The Management Service URL is unique to your namespace and looks similar to the following:

https://YOURNAMESPACE.accesscontrol.windows.net/v2/mgmt/service

Add the following declarations, where MyConsoleApplication is the name of your console application and MyServiceReference is the name of your service reference:

using System.Web;
using System.Net;
using System.Data.Services.Client;
using System.Collections.Specialized;
using System.Web.Script.Serialization;
using System.Globalization;
using System.Runtime.Serialization.Json; 
using MyConsoleApplication.MyServiceReference;

Add the following method to the Program class:

   public static ManagementService CreateManagementServiceClient()
        {
            string managementServiceEndpoint = String.Format(CultureInfo.InvariantCulture, "https://{0}.{1}/{2}",
                serviceNamespace,
                acsHostName,
                acsManagementServicesRelativeUrl);
            ManagementService managementService = new ManagementService(new Uri(managementServiceEndpoint));

            managementService.SendingRequest += GetTokenWithWritePermission;

            return managementService;
        }

Add the following code to the Program class to create GetTokenWithWritePermission method and its helper methods. GetTokenWithWritePermission and its helpers add the SWT OAuth token to the Authorization header of the HTTP request.

public static void GetTokenWithWritePermission(object sender, SendingRequestEventArgs args)
        {
            GetTokenWithWritePermission((HttpWebRequest)args.Request);
        }

        public static void GetTokenWithWritePermission(HttpWebRequest args)
        {
            if (cachedSwtToken == null)
            {
                cachedSwtToken = GetTokenFromACS();
            }

            args.Headers.Add(HttpRequestHeader.Authorization, "Bearer " + cachedSwtToken);
        }

        private static string GetTokenFromACS()
        {
            //
            // Request a token from ACS
            //
            WebClient client = new WebClient();
            client.BaseAddress = string.Format(CultureInfo.CurrentCulture, 
                                               "https://{0}.{1}", 
                                               serviceNamespace, 
                                               acsHostName);

            NameValueCollection values = new NameValueCollection();
            values.Add("grant_type", "client_credentials");
            values.Add("client_id", serviceIdentityUsernameForManagement);
            values.Add("client_secret", serviceIdentityPasswordForManagement);
            values.Add("scope", client.BaseAddress + acsManagementServicesRelativeUrl);

            byte[] responseBytes = client.UploadValues("/v2/OAuth2-13", "POST", values);

            string response = Encoding.UTF8.GetString(responseBytes);

            // Parse the JSON response and return the access token 
            JavaScriptSerializer serializer = new JavaScriptSerializer();

            Dictionary<string, object> decodedDictionary = serializer.DeserializeObject(response) as Dictionary<string, object>;

            return decodedDictionary["access_token"] as string;

        }

Initialize the Management Service client by adding the following code to the Main method in the Program class:

ManagementService svc = CreateManagementServiceClient();

Add your new rule group (you can call it “mygroup”, as shown in the code below) and save changes by adding the following code to the Main method in the Program class:

RuleGroup rg = new RuleGroup();
            rg.Name = "mygroup";
            svc.AddToRuleGroups(rg);
            svc.SaveChanges(SaveChangesOptions.Batch);

Establish a variable for "LOCAL AUTHORITY", which is a built-in issuer name that represents your Access Control namespace namespace, by adding the following code to the Main method in the Program class:

// "LOCAL AUTHORITY" is a built-in IDP name that represents the Access Control namespace. 
Issuer localAuthority = svc.Issuers.Where(m => m.Name == "LOCAL AUTHORITY").FirstOrDefault();

Do one of the following:

1. To add a basic rule, add the following code to the Main method in the Program class:
   
   
   Copy

   
               //EXAMPLE #1 - BASIC RULE
               Rule basicRule = new Rule()
               {
                   InputClaimType = "https://acs/your-input-type",
                   InputClaimValue = "inputValue",
                   OutputClaimType = "https://acs/your-output-type",
                   OutputClaimValue = "outputValue",
               };
   
               basicRule.Description = string.Format(CultureInfo.InvariantCulture,
                   "Transforms claim from {0} with type: {1}, value: {2}, into a new claim with type: {3}, value:{4}",
                   "ACS",
                   basicRule.InputClaimType,
                   basicRule.InputClaimValue,
                   basicRule.OutputClaimType,
                   basicRule.OutputClaimValue);
   
               svc.AddToRules(basicRule);
               svc.SetLink(basicRule, "RuleGroup", rg);
               svc.SetLink(basicRule, "Issuer", localAuthority);                                              
                 svc.SaveChanges(SaveChangesOptions.Batch);
   
   
   

2. To add a rule that passes through a specific input claim and value, add the following code to the Main method in the Program class:
   
   
   Copy

   //EXAMPLE #2 - PASSTHROUGH SPECIFIC TYPE AND VALUE RULE
               Rule passthroughSpecificClaimRule = new Rule()
               {
                   InputClaimType = "https://acs/your-input-type2",
                   InputClaimValue = "inputValue2",
               };
   
               passthroughSpecificClaimRule.Description = string.Format(CultureInfo.InvariantCulture,
                   "Passthough claim from {0} with type: {1}, value: {2}",
                   "ACS",
                   passthroughSpecificClaimRule.InputClaimType,
                   passthroughSpecificClaimRule.InputClaimValue);
   
               svc.AddToRules(passthroughSpecificClaimRule);
               svc.SetLink(passthroughSpecificClaimRule, "RuleGroup", rg);
               svc.SetLink(passthroughSpecificClaimRule, "Issuer", localAuthority); 
   svc.SaveChanges(SaveChangesOptions.Batch);
   
   

3. To add a rule that passes through the value of a specific input claim, add the following code to the Main method in the Program class:
   
   
   Copy

   //EXAMPLE #3 PASSTHROUGH SPECIFIC TYPE RULE
               Rule passthroughAnyClaimWithSpecificTypeRule = new Rule()
               {
                   InputClaimType = "https://acs/your-input-type3",
               };
   
               passthroughAnyClaimWithSpecificTypeRule.Description = string.Format(CultureInfo.InvariantCulture,
                   "Passthough claim from {0} with type: {1}, and any value",
                   "ACS",
                   passthroughSpecificClaimRule.InputClaimType);
   
               svc.AddToRules(passthroughAnyClaimWithSpecificTypeRule);
               svc.SetLink(passthroughAnyClaimWithSpecificTypeRule, "RuleGroup", rg);
               svc.SetLink(passthroughAnyClaimWithSpecificTypeRule, "Issuer", localAuthority); 
   svc.SaveChanges(SaveChangesOptions.Batch);
   
   

4. To add a rule that passes through any input claim that matches a specific value, add the following code to the Main method in the Program class:
   
   
   Copy

   //EXAMPLE #4 PASSTHROUGH ANY CLAIM W/SPECIFIC VALUE RULE
               Rule passthroughAnyClaimWithSpecificValueRule = new Rule()
               {
                   InputClaimValue = "inputValue3",
               };
   
               passthroughAnyClaimWithSpecificValueRule.Description = string.Format(CultureInfo.InvariantCulture,
                   "Passthough claim from {0} with any type, and specific value {1}",
                   "ACS",
                   passthroughSpecificClaimRule.InputClaimValue);
   
               svc.AddToRules(passthroughAnyClaimWithSpecificValueRule);
               svc.SetLink(passthroughAnyClaimWithSpecificValueRule, "RuleGroup", rg);
               svc.SetLink(passthroughAnyClaimWithSpecificValueRule, "Issuer", localAuthority); 
   svc.SaveChanges(SaveChangesOptions.Batch);
   
   

5. To add a rule that transforms a certain input claim type into a different output claim type but passes through (retains) the claim value, add the following code to the Main method in the Program class:
   
   
   Copy

   //EXAMPLE #5 COMPLEX RULE
               Rule complexTransformationRule = new Rule()
               {
                   InputClaimType = "https://acs/your-input-type4",
                   OutputClaimType = "https://acs/your-output-type2",
               };
   
               complexTransformationRule.Description = string.Format(CultureInfo.InvariantCulture,
                   "Transforms claim from {0} with type: {1}, and any value, into a new claim with type: {2}, keeping(passingthough) old value",
                   "ACS",
                   complexTransformationRule.InputClaimType,
                   complexTransformationRule.OutputClaimType);
   
               svc.AddToRules(complexTransformationRule);
               svc.SetLink(complexTransformationRule, "RuleGroup", rg);
               svc.SetLink(complexTransformationRule, "Issuer", localAuthority);
   
               svc.SaveChanges(SaveChangesOptions.Batch);
