Hi Bruno,
Base on your post, we can try to use the “FORM” authentication mode to instead of the Windows integrated to see there is any improvement.
Please follow the steps below to perform the activity.
1. Connect to your ADFS server.
2. Go to “C:\inetpub\adfs\ls” and open “web.config” via notepad.
3. Change the order of the Authentication Types
<localAuthenticationTypes>
<add name=”Forms” page=”FormsSignIn.aspx”/>
<add name="Integrated" page="auth/integrated/" />
<add name="TlsClient" page="auth/sslclient/" />
<add name="Basic" page="auth/basic/" />
</localAuthenticationTypes>
Please let me know whether this works or not.
Thanks,
Yang Yu
