This document provides an overview of Azure Active Directory (Azure AD) and how to use the Azure AD Graph API. It discusses how Azure AD extends an on-premises Active Directory to the cloud for authentication and identity management. It also summarizes how to register an application with Azure AD, obtain authentication tokens, and perform CRUD operations on directory objects like users and groups via the Graph API using libraries, REST calls, and samples.

- 1. Programming Azure Active Directory
- 3. 17 COLUMBUS, OH OCTOBER 17, 2014 CLOUDDEVELOP.ORG
- 4. Opening Keynote Scott Guthrie October 21st, 2014 8:00am – 5:00pm PST http://azureconf.net
- 5. Assume you know what Microsoft Azure is and likely have an Azure subscription. This is not a Active Directory design session. Review common scenarios . . . Yours may be different. We’re not going to cover it all today . . . large, complicated topics with many options/scenarios.
- 6. Azure Active Directory - What is it?
- 7. Multi-tenant “directory-as-a-service” Identity & access for on-premises and cloud applications NOT a cloud version of Windows Server AD Image Source: http://technet.microsoft.com/en-us/library/jj573650.aspx
- 8. Extend Windows Server AD to the cloud Directory & identity services w/o need for Windows Server AD Each O365 tenant has instance of AAD Your App AAD Authentication platform Directory store Active Directory
- 9. Register an application with Azure AD Permissions Open source Azure AD authentication libraries
- 11. Visual Studio 2013 wizard makes it easy Register the application in Azure AD Set a database Set Sign-On URL, App ID and Reply URL Basic set of claims available from AAD
- 12. Working with the Graph
- 13. Read
- 14. Read Write
- 16. REST API Endpoints Authentication with Azure AD
- 17. REST API Endpoints Authentication with Azure AD Role Based Access Control (RBAC)
- 18. REST API Endpoints Authentication with Azure AD Role Based Access Control (RBAC) Differential Queries
- 19. REST API Endpoints Authentication with Azure AD Role Based Access Control (RBAC) Differential Queries Directory Extensions
- 20. What’s in the directory? REST Graph API
- 21. Graph URL Tenant (domain or objectID) https://graph.windows.net/ Entity (user, group, role, etc) ?$filter=givenName eq 'Jon'&api-version=2013-11-08 OData query ($filter, $top) collierdemo.onmicrosoft.com/ API Version users
- 22. Active Directory Authentication Library (ADAL) for .NET
- 24. Graph Security
- 25. My Application Service-to-Service OAuth 2.0 Grant Type Client Credentials Azure AD Authentication Endpoint (OAuth) (https://graph.windows.net) REST Service (validates token, process, returns data) Authorization Check Azure Active Directory 1) Request JWT token (provide clienID and secret) 2) Return JWT token 3) HTTP Request w/ JWT token 4) Return response
- 26. OAuth 2.0 Grant Type = Client Credentials // get OAuth token using Client Credentials string tenantName = "GraphDir1.onMicrosoft.com"; string issuingAuthority = "https://login.windows.net/" + tenantName; AuthenticationContext authenticationContext = new AuthenticationContext(issuingAuthority,false); // Config for OAuth client credentials string clientId = "118473c2-7619-46e3-a8e4-6da8d5f56e12"; string clientSecret = "hOrJ0r0TZ4GQ3obp+vk3FZ7JBVP+TX353kNo6QwNq7Q="; ClientCredential clientCred = new ClientCredential(clientId, clientSecret); string resource = "https://graph.windows.net"; string token; AuthenticationResult authenticationResult = authenticationContext.AcquireToken(resource, clientCred); token = authenticationResult.AccessToken; * Some values removed for readability OAuth 2.0 grant type, client_id, and client_secret configured in Azure portal
- 27. OAuth 2.0 Grant Type = Client Credentials POST https://login.windows.net/GraphDir1.onMicrosoft.com/oauth2/token Content-Type: application/x-www-form-urlencoded client-request-id: 1e38c3d3-dca3-42ff-8149-5db607b3488c return-client-request-id: true resource=https%3A%2F%2Fgraph.windows.net& client_id=118473c2-7619-46e3-a8e4-6da8d5f56e12& client_secret=hOrJ0r0TZ4GQ3obp%2Bvk3FZ7JBVP%2BTX353kNo6QwNq7Q%3D& grant_type=client_credentials * Some values removed for readability

- 30. 1. Leverage ADAL and Graph Library 2. Obtain authentication token 3. Set GraphSetting with API version of choice 4. Set filter properties (if desired) 5. Get, Create, or Delete User, Group, Application, etc.
- 31. Provide means to bring on-premises / custom schema extensions to Azure AD.
- 33. 1. Obtain authentication token 2. Write against REST API directly 3. Ability to set custom properties on directory objects
- 34. Azure AD extends directory authentication to the cloud Enables single sign-on for web applications CRUD objects in the directory

Editor's Notes
- Show via Azure management portal Sign up for Azure AD Delete a tenant Register a new application in Azure AD Set for single sign-on mcadmin@collierdemo.onmicrosoft.com / test!123
- The Check Group Membership operation is performed by invoking the IsMemberOf function on the directory service. This function returns a Boolean value that indicates whether a specified user, group, or contact is a member of a specified group. The operation is transitive, that is, if User A is a member of Group B and Group B is a member of Group C and the function is invoked with User A and Group C as parameters, it will return true. You can contrast this with the memberOf navigation property for User A, which is intransitive and would therefore not return Group C in its result set because User A is a member of Group C only through its membership in Group B. http://msdn.microsoft.com/en-us/library/azure/dn151601.aspx
- DirectoryObject is the base type for the following entity types: Application, Device,DirectoryLinkChange, Contact, Group, Role, ServicePrincipal, TenantDetail, and User. http://msdn.microsoft.com/en-us/library/windowsazure/jj134105.aspx

- These are the four primary application scenarios supported by Azure AD: • Web Browser to Web Application: A user needs to sign in to a web application that is secured by Azure AD. • Native Application to Web API: A native application that runs on a phone, tablet, or PC needs to authenticate a user to get resources from a web API that is secured by Azure AD. • Web Application to Web API: A web application needs to get resources from a web API secured by Azure AD. • Daemon or Server Application to Web API: A daemon application or a server application with no web user interface needs to get resources from a web API secured by Azure AD. http://msdn.microsoft.com/en-us/library/azure/dn499820.aspx
