SSO Issue Two Logins

SSO Issue Two Logins

Dear all,

I have installed Manage Engine on a Windows Server 2008R2. Build is the latest 9.0 Build 9006. Everything works as it should except the SSO login with the windows-credentials. When I open the webinterface, it comes up with a login screen from windows, I insert my user credentials and will be forwarded to the login screen from SD+ itself. There I have to insert the credentials again. After that, I am succesfully logged on to the application.
I have tried different browser, but still the same. The SSO log doesn't come up with a error message, but it says, my user was successfully authenticated.

Thanks in advance for any help!
Kid Regards.
