Blog reader Michael F. pointed this out to me over the weekend (thanks for that). Actually affected administrators should know about it, but Michael writes:

some of my domain admins reacted a bit surprised to the message and said: yes, we already know that, but also only recently.

Michael send me links to some German articles asked me if I could remind admins within my blog. Microsoft has covered the whole topic within ADV190023 (Microsoft Guidance for Enabling LDAP Channel Binding and LDAP Signing) – see also my blog post Microsoft Security Advisories Dez. 17, 2019. Addendum: Seems it’s postphoned until March 2020.
