Duuuuude why did you migrate the entire company to Entra with a ton of resources that are never leaving the on-prem domain and a bunch of Mac users that don’t have credential manager or runas.exe to help them hop domains to access those on-prem resources?

Then there’s the refusal to build a forest trust between Entra and the on-prem domain which is fucking baffling to me.

Also farming the entirety of this troubleshooting out to the Principal Data Architect instead of figuring it the fuck out yourself is beyond annoying. I was last a sysadmin 20 goddamned years ago.

The Rumba Identity Platform got a small logo. I'm not a pro at this stuff but it's at least what I feel Rumba is about.

Work currently is focused on two areas:

- we are pushing Rumba through the Samba self-test which is a bit infamous
- we are doing virtualized client tests against Windows systems and Linux systems running #himmelblau

A fun thing here: we do test against Windows starting with the Windows 2000 client because we can.

A rough watch for any Windows admin: this demo goes from standard user to Domain Admin by chaining insecure AD permissions with an ESC1-style certificate template issue. The point is not flashy hacking; it is that these mistakes are still common in real environments.

How often are AD delegations and certificate templates actually reviewed?
