[Samba] RSAT not working any more?

[Thomas Kamalakis]

Dear all

  I am having trouble administering Samba DC using RSAT on a Windows 10
machine.

  Installation info:
  Samba version: 4.14.9 (installed fresh from source on an Ubuntu 20.04).
  Windows 10 client: Windows 10 Pro (21H1 - OS build 19043.1288)
  RSAT server manager: Build number 10.0.19041.1 / 12-6-2019

  Server manager identifies the server running the "Samba" operating system
and then reports "Error - Cannot manage the operating system of the target
computer"

  The Windows 10 client has successfully joined the domain and I am logged
in as Administrator at DOMAIN.EXAMPLE.COM without any problems.

  DNS is working on the DC, and I am correctly resolving the LDAP and
kerberos services as well as the dc name dc1.domain.example.com

  I've also tried the Ubuntu 20.04 samba version (4.11.6) on a clean
install and behavior is the same. Clean installing Samba 4.15 was worse,
Administrator could not login, it seems this is a widespread problem for
the 4.15, this is why I ended up building the 4.14.9

  Does any one have any suggestions? I remember RSAT working fine with
earlier Windows and Samba versions.

  BR

  Thomas
