Skype for Business登录弹出窗口

Question

I have an application that uses Skype For Business in UI suppression mode.

When logging in using the following code (in UI suppressed):

await Task.Factory.FromAsync((callback, stateObject) => _client.BeginSignIn(config.SkypeUserUri, config.SkypeDomainAndUsername, config.SkypePassword, callback, stateObject), _client.EndSignIn, null);

The application just hangs and never gets any further.

If I try the same code without UI suppression. I'm seeing this pop-up password request. Rather than the normal password window Skype For Business uses.

It appears this pop-up is preventing the Skype From Business SDK from logging in. I have checked the credentials and everything seems okay. I don't seem to be able to get past it.

Any ideas what is going on here?

I believe this guy might be having the same issue: Lync Client SDK - Ui suppression - Client stuck at SigningIn State

Answer 1

This happens if: 1) ModernAuthentication is enabled in your office365 tenant 2) EnableADAL = 1 if you are using SkypeForBusiness2015 client 2015 3) If you are using SkypeForBusiness2016 client

Applicable only to SfB prior to 2016 HKCU\\SOFTWARE\\Microsoft\\Office\\15.0\\Common\\Identity\\EnableADAL If you want to bypass this pop-up, then you need to add EnableADAL registry key and set its value to 0.
