Teams Bot with SSO

Teams Bot with SSO using Bot Framework v4.

This bot has been created using Bot Framework, it shows how to get started with SSO in a bot for Microsoft Teams.

The focus of this sample is how to use the Bot Framework support for OAuth SSO in your bot. Teams behaves slightly differently than other channels in this regard. Specifically an Invoke Activity is sent to the bot rather than the Event Activity used by other channels. This Invoke Activity must be forwarded to the dialog if the OAuthPrompt is being used. This is done by subclassing the ActivityHandler and this sample includes a reusable TeamsActivityHandler. This class is a candidate for future inclusion in the Bot Framework SDK.

The sample uses the bot authentication capabilities in Azure Bot Service, providing features to make it easier to develop a bot that authenticates users to various identity providers such as Azure AD (Azure Active Directory), GitHub, Uber, etc. The OAuth token is then used to make basic Microsoft Graph queries.

IMPORTANT: The manifest file in this app adds "token.botframework.com" to the list of validDomains. This must be included in any bot that uses the Bot Framework OAuth flow.

Prerequisites

  • Microsoft Teams is installed and you have an account (not a guest account)
  • NodeJS
  • ngrok or equivalent tunneling solution
  • M365 developer account or access to a Teams account with the appropriate permissions to install an app.

To try this sample

Note these instructions are for running the sample on your local machine, the tunnelling solution is required because the Teams service needs to call into the bot.

1. Setup for Bot SSO

Refer to Bot SSO Setup document.

2. Configure bot sample

Update the appsettings.json configuration for the bot to use the Microsoft App Id and App Password from the Bot Framework registration. (Note the MicrosoftAppId is the AppId created in step 1.1, the MicrosoftAppPassword is referred to as the "client secret" in step1.2 and you can always create a new client secret anytime.)

3. Run your bot sample

  • Clone the repository

    git clone https://github.com/OfficeDev/Microsoft-Teams-Samples.git

  • If you are using Visual Studio

    • Launch Visual Studio
    • File -> Open -> Project/Solution
    • Navigate to samples/bot-conversation-sso-quickstart/csharp_dotnetcore folder
    • Select TeamsAuth.csproj file
    • Press F5 to run this project

4. Configure and run the Teams app

  • Using App Studio

    • Open your app in App Studio's manifest editor.
    • Open the Bots page under Capabilities.
    • Choose Setup, then choose the existing bot option. Enter your AAD app registration ID from step 1.1. Select any of the scopes you wish to have the bot be installed.
    • Open Domains and permissions from under Finish. Enter the same ID from the step above in AAD App ID, then and append it to "api://botid-" and enter the URI into Single-Sign-On.
    • Open Test and distribute, then select Install.

  • Manually update the manifest.json

    • Edit the manifest.json contained in the appPackage/ folder to replace with your MicrosoftAppId (that was created in step1.1 and is the same value of MicrosoftAppId in appsettings.json file) everywhere you see the place holder string {TODO: MicrosoftAppId} (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json). The ConnectionName is the name of OAuth Connection you configured in step3.
    • Zip up the contents of the appPackage/ folder to create a manifest.zip
    • Upload the manifest.zip to Teams (in the left-bottom Apps view, click "Upload a custom app")

You can interact with this bot by sending it a message. The bot will respond by asking for your consent, by this consent the Bot will exchange an SSO token, then making a call to the Graph API on your behalf and returning the results. It will keep you loggined unless you send a message "logout".
