This error is related with the error in ADFS 2.0 in the post: https://sharepointrescue.wordpress.com/2015/11/05/adfs-2-0-chrome-users-repeteadly-prompted-for-credentials/
But in this case we are working with ADFS 3.0 so we don’t use IIS anymore, but there are other default settings working against Our Chrome users, so lets have a look at what we need to change.
Chrome only uses NTLM Authentication, so first we need to allow this by setting the ExtendedProtectionTokenCheck to None.
Set-ADFSProperties –ExtendedProtectionTokenCheck None
Then we need to alter the current list of supported user-agents for NTLM, which basicly means we need to allow Chrome within the list of browser we want to support. Get the list over allready supported browsers:
Get-ADFSProperties | Select -ExpandProperty WIASupportedUserAgents
It will show a list of supported browser which by default is:
Then we add all these and Chrome, or to be Clear, we add what ADFS think Chrome is:
Set-ADFSProperties -WIASupportedUserAgents @(“MSIE 6.0″, “MSIE 7.0″, “MSIE 8.0″, “MSIE 9.0″, “MSIE 10.0″, “Trident/7.0″, “MSIPC”, “Windows Rights Management Client”, “Mozilla/5.0“)
Which is Mozilla v5.0, then restart the Active Directory Federation Service to use the changes.

We’ve done this for our implementation, and we are still recieving the prompts. Any ideas?

Hey Murphy, are you using ADFS 2.1 or 3.0? In which explorer where the problem reproduced? Try the solution explained here: https://sharepointrescue.wordpress.com/2015/11/05/adfs-2-0-chrome-users-repeteadly-prompted-for-credentials/ to set the Extended Protection to Off in IIS

We are using ADFS 3 and trying to get Chrome to work.

Ok, this problem happens internally, only in the proxy or in both servers? If you have followed the PS steps, check If the adfs service has been restarted in both servers
