Web Client and Web.Config settings

Has anyone actually got the "Link" settings in the web.config to work recently? We have the following in the web.config.

I have set mine as below for testing.

When I go to the login page I only see the Privacy link in Dynamics NAV Web Client and none of the others. The Privacy one does link to mibuso so I know this config is being referred to somehow "under the hood"

<add key="FeedbackLink" value="http://forum.mibuso.com&quot; />
<add key="CommunityLink" value="http://forum.mibuso.com&quot; />
<add key="PrivacyLink" value="http://forum.mibuso.com&quot; />
<add key="LegalLink" value="http://forum.mibuso.com&quot; />

Feedback, Community and Legal never appear.

The documentation on MSDN also mentions a ForgotPasswordLink which I do not see in the Web.config.

I have added it as per the below but still no joy with getting this to appear at all on the sign in page.

<add key="ForgotPasswordLink" value="http://www.bbc.co.uk&quot; />

Anyone else have experience with this, as it seems quite simple but does not seem to work. I am on NAV 2017 latest CU.

Thanks in advance,

Ade
