Hi Team,
I have a worry to use ModernAuthentication with Aspose.Email.
I register my application in azure directory as a “delegate authentication”
I have settings for the authentication :
client_id = “client-id-from-registration”,
tenant_id = “tenant-id-from-registration”,
scopes = “Sign in to Outlook”
To retrieve the token, I wrote thing like this :
private readonly IPublicClientApplication _clientApplication;
_clientApplication = PublicClientApplicationBuilder
.Create(clientId)
.WithTenantId(tenantId)
.WithRedirectUri(“http://localhost”)
.Build();
var result = await _confidentialClientApplication.AcquireTokenByUsernamePassword(_scopes, “email”, “pwd”))
.ExecuteAsync();
where email and pwd are credentials for my mail box.
The system generates the token, but if I use the generated token like this ;
using ImapClient client = new()
{
Host = host,
Username = username,
Password = result.AccessToken,
Port = port,
SecurityOptions = useSsl ? SecurityOptions.SSLAuto : SecurityOptions.None,
Timeout = 30000
};
bool isValidCredentials = false;
try
{
isValidCredentials = await client.ValidateCredentialsAsync();
}
catch (Exception ex)
{
throw ex;
}
return isValidCredentials;
The method always pass through Exception. And this exception said only : “connect failure”
If I change AcquireTokenByUsernamePassword with AcquireTokenInteractive, the token isn’t generated with a message like : client-secret is required.
I don’t understand why things are not working… Any ideas ?
