Web filtering not picking up user

Have run these commands but authentication log still not loading

service -ds nosync nasm:stop
rm -rf /content/nasm
service -ds nosync nasm:start

You should not run some random comments without verifying the issue first. 

The reporting issue seems to be a database issue with logviewer (Garner). 

Would recommend to create a support case, so this can be verified. 

According to support I have to reconfigure all my servers and set them up to use a proxy server.

Surely this isn't required and Sophos is able to identify users just as it used to do?

Actually it is? 

So to recap: 

You can do two different things to authenticate a terminal server: 

You can use Intercept X for Server, which uses a component like SATC. So no changes in behavior there.

You can use no software on the server and resolve this with the explicit proxy + kerberos. This is the new feature of V19.0. See: https://docs.sophos.com/nsg/sophos-firewall/19.0/Help/en-us/webhelp/onlinehelp/AdministratorHelp/Authentication/HowToArticles/AuthenticationConfigurePerConnectionAuth/index.html#create-firewall-rules-for-multi-user-host-traffic  You can use per-connection AD SSO authentication for multi-user hosts configured to use the Firewall as a direct proxy.

Using a proxy is not an option for the client, so I talked to them and convinced them to purchase Intercept X which is now installed, but there is still no authentication happening.
