[Samba] Delegation of control failure for any built-in Security Principals

Hi Rowland.
The answers to your questions:
- Yes, it works fine with any other normal user (non-built in users), including the domain administrator user.A. I'm referring to Debian architecture like that, because that's exactly what's returned by  'uname -m' -> aarch64B. I prefer to build by myself, in order to disable all the stuff which I know that I do not need for sure: printing support, avahi, dmapi, systemd support, clustering, glusterfs.
Any ideas on how I can dig into this problem further?Here's my smb.conf:
        allow dns updates = secure only
        bind interfaces only = Yes
        disable spoolss = Yes
        interfaces = eth0
        ldap server require strong auth = Yes
        netbios name = DC
        ntlm auth = mschapv2-and-ntlmv2-only
        printcap name = /dev/null
        realm = DOMAIN.ORG
        restrict anonymous = 2
        server min protocol = SMB3
        server role = active directory domain controller
        tls cafile = tls/bundle_ca.crt
        tls certfile = tls/dc.crt
        tls enabled = Yes
        tls keyfile = tls/dc.key
        wins server =
        wins support = Yes
        workgroup = DOMAIN
        idmap_ldb:use rfc2307 = yes
        comment = "Domain Controller for domain.org"

 Hi team.

I am trying to allocate some rights to users in Active Directory, by using the "Delegation of Control Wizard" from ADUC.
The steps I'm following were executed under the domain administrator user and are the following:

1. open ADUC and right click the top level OU (Ex. domain.org)
2. from the pop-up menu, select “Delegate Control…”
3. click next in the first page of the wizard (which is the "Welcome" page)
4. on the next page "Users or Groups", select the “Add” button, and type ‘SELF’ then ‘Check Names’.
5. I'm getting an error window with the following message:
    "Windows cannot process the object with the name "SELF" because of the following error:
    Name translation: Input name found, but not the associated output format.
After the error, I am unable to continue with the wizard to delegate tasks.The same error appears if I try to select any other built in security principals like: Everyone or SYSTEM, etc
The logs show nothing suspicious (with log level 10).
The only log entry which I've found and looked strange to me was this one:
    gendb_search_v: CN=Self,CN=WellKnown Security Principals,CN=Configuration,DC=domain,DC=org NULL -> 1

Any ideas on what might be wrong?

The platform I'm using:
  Software:      Samba Version 4.17.4 (built from source)
  OS:               Debian GNU/Linux 11 (bullseye)
  Architecture:     aarch64
  Kernel:           5.15.84-v8+
Thanks a lot.Sorin
