Is not posible to join Ubuntu machines to a domain based on Windows Server 2025 (using realm at least) this is the error:

adcli: joining domain xxxx.de failed: Couldn't set password for computer account: XXXX$: Message stream modified

Domain is discoverable vía realm:

realm-name: xxx.DE
domain-name: xxx.de
configured: no
server-software: active-directory
client-software: sssd
required-package: sssd-tools
required-package: sssd
required-package: libnss-sss

Tested on WS2025 build 10.0.26100.2033 and Linux Ubuntu 24.04 LTS.

What do your configs look like?
Have you tried it with classic samba + winbind ?
Is your 2025 ADDC perhaps restricted --> Windows Firewall, what does the EventLog say when the joining attempt happens?
