Configuring Microsoft Modern Authentication (OAuth 2.0) for FogBugz On Premise


Follow

Overview

OAuth support for accessing O365/outlook.com (EWS) mailboxes using modern authentication is now available for FogBugz (8.22.635 above).

 


Information

Microsoft is deprecating basic authentication in Exchange Online. Refer to this article for more information surrounding this: https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/deprecation-of-basic-authentication-exchange-online

 

To overcome this, FogBugz has adopted modern authentication (OAuth 2.0 token-based authorization). This guideline is created for FogBugz on premise customers to assist them in performing the changes required to support modern authentication.

 

Download the latest version of Fogbugz on premise and perform an upgrade, then go through the following steps to complete the set up.

 

1. Register your FogBugz application using the Azure app registration portal. You can use either a Microsoft account or a work or school account to register.

2. In the App registrations portal, click on New registration.

3. Enter a display Name for your FogBugz application. This name will be seen by FogBugz users when signing in using modern authentication.

4. Specify who can use the FogBugz application, sometimes called its sign-in audience.

Take note of the redirect URI as this is needed when updating the registry editor later on.

6. Once the registration is completed, take note of the client id and tenant id. We are going to need these 2 values when updating the registry editor later on.

18. Add the following 4 sets of registry values into the FogBugz registry directory. The value type should be a string value.

"sOAuthExchangeOnlineTenantId"="your_azure_tenant_id"

"sOAuthExchangeOnlineRedirectUrl"="https://<your FogBugz URL>/oauthresult.aspx"
