VMM 2016 and Network Controller certificate Issue’s

Since near the end of last year I was blessed with some hardware to test al lot of new features and stuff of Windows Server 2016, System Center 2016 and Azure Stack. Last week I experienced an issue with my Network Controller VM’s. In the end it turned out to be more of a VMM issue I think. But I wanted to share this with the world in case somebody else experienced this issue and does google for nothing because there is nothing to find about this issue.

Problem

I did the network controller and SLB Mux setup several weeks ago and all was running fine while all of a sudden I couldn’t change stuff in VMM anymore. Almost every action I did triggered this error:

ADFS on W2016 idpinitiatedsignon.aspx page is by default disabled

Everytime I experience ADFS sign in problems I first test if the ADFS service itself is working through the IdpInitiatedSignon.aspx page. With this page you can test the ADFS service itself with out the dependencies from other products and their trusts or relying parties.

With the new Windows Server 2016 ADFS and WAP (Windows Azure Pack) on 2016 I experienced an issue, so I wanted to use the IdpInitiatedSignon.aspx test page. Strangely I received an error on the test page.
