Delegating domain join privileges in Samba 4 from the command line (or not)

I'm trying to solve a bit of a mystery. I'd like to set up Samba 4 without using Windows. Most things seem to be possible, but I can't figure out how to delegate domain join privileges. Unfortunately, even the official documentation specifically references ADUC.

So I did some digging into what it would take to delegate domain join privileges without a Windows system. After several dead ends, I ran across this page: https://www.sevecek.com/EnglishPages/Lists/Posts/Post.aspx?ID=48

The important bit of that page is this script that uses the Windows command-line tool dsacls:

$user = 'gps\SCCM Client Computer Joiners'  $ou = 'OU=SCCM Test Clients,OU=SCCM,OU=Service,OU=Company,DC=gopas,DC=virtual'    DSACLS $ou /R $user    DSACLS $ou /I:S /G "$($user):GR;;computer"  DSACLS $ou /I:S /G "$($user):CA;Reset Password;computer"  DSACLS $ou /I:S /G "$($user):WP;pwdLastSet;computer"  DSACLS $ou /I:S /G "$($user):WP;Logon Information;computer"  DSACLS $ou /I:S /G "$($user):WP;description;computer"  DSACLS $ou /I:S /G "$($user):WP;displayName;computer"  DSACLS $ou /I:S /G "$($user):WP;sAMAccountName;computer"  DSACLS $ou /I:S /G "$($user):WP;DNS Host Name Attributes;computer"  DSACLS $ou /I:S /G "$($user):WP;Account Restrictions;computer"  DSACLS $ou /I:S /G "$($user):WP;servicePrincipalName;computer"  DSACLS $ou /I:S /G "$($user):CC;computer;organizationalUnit"

samba-tool has a subcommand dsacl set that I thought might be able to accomplish the same task. After a lot of work trying to get the arguments correct, I got to this point:

[root@dc1 ~]# samba-tool dsacl set --action=allow --objectdn='cn=Computers,dc=samba4,dc=local' --trusteedn='cn=Domain Join,cn=Users,dc=samba4,dc=local' --sddl='GR;;computer' --realm=SAMBA4.LOCAL -U administrator --password="$( cat /root/.password )"
new descriptor for cn=Computers,dc=samba4,dc=local:

So... I think the arguments to dsacls are some kind of "friendly" names that resolve to UUIDs or SIDs or something on the back end, but I can't figure out how to do the mapping.

Appreciating you putting your thoughts out there. This helped me get started on the problem and I think I figured it out. I ended up using the Windows GUI to make the delegation per Samba's instructions and compared the changes before/after to get this:

SID="GroupSIDHere"
samba-tool dsacl set --action=allow --objectdn='cn=Computers,dc=directory,dc=example,dc=com' --sddl="(OA;CI;CCDC;BF967A86-0DE6-11D0-A285-00AA003049E2;;$SID)(OA;CIIO;SWWP;F3A64788-5306-11D1-A9C5-0000F80367C1;BF967A86-0DE6-11D0-A285-00AA003049E2;$SID)(OA;CIIO;SWRPWP;72E39547-7B18-11D1-ADEF-00C04FD8D5CD;BF967A86-0DE6-11D0-A285-00AA003049E2;$SID)(OA;CIIO;RPWP;4C164200-20C0-11D0-A768-00AA006E0529;BF967A86-0DE6-11D0-A285-00AA003049E2;$SID)(OA;CIIO;CR;00299570-246D-11D0-A768-00AA006E0529;BF967A86-0DE6-11D0-A285-00AA003049E2;$SID)"
