How to Connect to Microsoft Dynamics 365 for Finance and Operations (on-premises)

Here i am going to explain the simple trick to connected to Microsoft Dynamics 365 for Finance and Operations (on-premises).

For this, we need to modify on the Dynamics365Connector.cs in DynamicwebConnectorService

here is the current code to get authentication

private string GetAuthenticationHeader(NameValueCollection connectorSettings)

{

string activeDirectoryTenant = connectorSettings["ActiveDirectoryTenant"];

string activeDirectoryClientAppId = connectorSettings["ActiveDirectoryClientAppId"];

string activeDirectoryResource = connectorSettings["ActiveDirectoryResource"];

string activeDirectoryClientAppSecret = connectorSettings["ActiveDirectoryClientAppSecret"];

var credential = new ClientCredential(activeDirectoryClientAppId, activeDirectoryClientAppSecret);

AuthenticationContext authenticationContext = new AuthenticationContext(activeDirectoryTenant);

AuthenticationResult authenticationResult = authenticationContext.AcquireTokenAsync(activeDirectoryResource, credential).Result;

return authenticationResult.CreateAuthorizationHeader();

}

In this code, we hit "Authority validation is not supported for this type of authority Parameter name: validateAuthority"

When you create AuthenticationContext it checking ValidateAuthority property as default, When we connect to On-Premises we need to disable that checking with a following code update

AuthenticationContext authenticationContext = new AuthenticationContext(activeDirectoryTenant, false);

Hope this will help to you guys in future development

Thanks and Happy Coding
