How do I patch/hotfix the MIM 2016 password registration/reset features?

I installed MIM 2016 from media. Installed MIM Portal/service, Password Registration, Password Reset and MIM Sync. Tested OK.

I did not install any add-ins or extensions.

Then I obtained the latest hotfix and patched the MIM Service and MIM Sync (now on build 4.3.2266.0)

Since then I have had hard times getting the Password Registration to work without 401 errors. I do not see in the Hotfix492580 folder any patch installers for Password Registration and/or Password reset. Are there any?

The only way I have found to get the Password registration to work once more is to switch in IIS8 the order Negotiate NTLM to be NTLM Negotiate.

The documentation says I should keep all parts of MIM at the same patch level... where is the PW reg hotfix???
