ADFS - Windows authentication

One of my clients is using Microsoft ADFS as their Security Token Service. Through ADFS people can login either by using their e-id(Belgian passport) or through their internal domain account (using Windows authentication).

After upgrading our ADFS server, we noticed that people were asked for their credentials and that their windows credentials were not passed automatically.

This is of course quite annoying.

We took a look at the ADFS settings and noticed that ‘mozilla/5.0’ was missing from the list of user agents:

PS C:\Users\bawu> (Get-AdfsProperties).Wiasupporteduseragents

MSAuthHost/1.0/In-Domain

MSIE 6.0

MSIE 7.0

MSIE 8.0

MSIE 9.0

MSIE 10.0

Trident/7.0

MSIPC

Windows Rights Management Client

MS_WorkFoldersClient

=~Windows\s*NT.*Edge

To fix it we updated the list of supported agents:

Set-ADFSProperties -WIASupportedUserAgents @("MSAuthHost/1.0/In-Domain","MSIE 6.0", "MSIE 7.0", "MSIE 8.0", "MSIE 9.0", "MSIE 10.0", "Trident/7.0", "MSIPC", "Windows Rights Management Client", "MS_WorkFoldersClient", "=~Windows\s*NT.*Edge", "Mozilla/5.0")

That did the trick!

Help! I accidently enabled HSTS–on localhost

I ran into an issue after accidently enabling HSTS for a website on localhost. This was not an issue for the original website that was running in IIS and had a certificate configured. But when I tried to run an Angular app a little bit later on http://localhost:4200 the browser redirected me immediately to https://localhost . Whoops! That was not what I wanted in this case. To fix it, you need to go the network settings of your browser, there are available at: chrome://net-internals/#hsts edge://net-internals/#hsts brave://net-internals/#hsts Enter ‘localhost’ in the domain textbox under the Delete domain security policies section and hit Delete . That should do the trick…
