It really grinds me gears when Teams meeting organizers do not force end meetings when they are over, and people that walked away or fell asleep stay stuck in the meeting for hours, leaving the camera icon there saying there's an active meeting.

TIL that you need DA to view RODC password replication policy results (was testing/verifying for AzureADKerberos). @josephryanries.bsky.social maybe you know why, seems odd, thought that would fall under typical RO directory data for domain users.

If you were to trust their root CA as instructed, anything it issues would be inherently trusted by your device.

Anthony J. Fontanez @ajf8729.com · 10/07/2025
This is actually hilarious and no, you shouldn't blindly trust some root CA like this. This defeats the purpose of how PKI works. Public CAs are heavily regulated in terms of auditing and security.

Notepad++'s code signing cert expired, couldn't get a new one under the "Notepad++" name, so instead of getting one under their name (what the WinSCP developer does), they instead created their own root CA, issued a code signing cert, and want you to trust it notepad-plus-plus.org/news/v883-se...

Oh I'll bet all of those other roles will hybrid join fine. I think if you sync a DC, it will hybrid join, but not sure if it causes any issues; def not supported. It might be blocked/prevented somehow now, but I'm pretty sure I did it by accident in a lab many years ago.
