We will like to know how should we proceed from here?

We are using an isolated on-prem environment.

The patch we used is
https://www.catalog.update.microsoft.com/Search.aspx?q=KB5007192
(For windows server)

Do we need to install a KB5008601 on top of this patch to fix this?

    This update is not known to cause issues with LDAPs but with Kerberos constraint delegation. Are you sure that the problem you are sseing is LDAPs related? Can you explain what is the issue in your case?
