Active Directory schema extension issue if you use a Windows Server 2025 schema master role

Hi,

First, thank you for informing us. Sadly enough, this is highly inconvenient for us. Recently we introduced for many of our Customers 2025 DC's because we had to deal with strong certificate mapping. 
Thinking about it though, it generally should not be too much of an issue to temporarily borrow another server to promote it to DC and do this.
Still, it would be much appreciated if we could be provided publicly with the script support has to clean up duplicates in the schema. It would save me (and others) the hassle should we encounter the issue.
