[Samba] BUILTIN\Administrators - failed to call wbcSidToUid: WBC_ERR_DOMAIN_NOT_FOUND

[Jiří Černý]

Hello everyone.
I'm trying to fix sysvol rights, because i see errors in output of
/usr/bin/samba-tool ntacl sysvolcheck
ERROR(<class 'samba.provision.ProvisioningError'>): uncaught exception
- ProvisioningError: DB ACL on GPO directory

That's nothing new, this was disused here many times.

Today, I decided to try script
(https://github.com/thctlo/samba4/blob/master/samba-check-set-sysvol.sh)
by mr. van Belle and I ended with this error:
failed to call wbcSidToUid: WBC_ERR_DOMAIN_NOT_FOUND
Could not convert sid S-1-5-32-544 to uid

Confirmed:
wbinfo --sid-to-uid=S-1-5-32-544
failed to call wbcSidToUid: WBC_ERR_DOMAIN_NOT_FOUND
Could not convert sid S-1-5-32-544 to uid

So I have problem with builtin group Administrators, other groups look
good:
wbinfo --sid-to-uid=S-1-5-32-549
15543
wbinfo --sid-to-uid=S-1-5-11
15549

DB seems to be ok:
samba-tool dbcheck --cross-ncs --fix
Checking 5227 objects
Checked 5227 objects (0 errors)

Is there any way to fix my domain?

I have AD migrated from Samba 3 NT (migrated to SerNet Samba 4.2).
Running now on 2 CentOS6 DCs, SerNet Samba 4.6.7.
Here is my DS's smb.conf:
# Global parameters
[global]
 workgroup = COMPANY
 realm = samdom.company.cz
 netbios name = DC01
 server role = active directory domain controller
 idmap_ldb:use rfc2307 = yes
 dns forwarder = 192.168.1.34
 allow dns updates = nonsecure
 log level = 1
 load printers = no
 printing = bsd
 printcap name = /dev/null
 disable spoolss = yes

[netlogon]
 path = /var/lib/samba/sysvol/samdom.company.cz/scripts
 read only = No
 acl_xattr:ignore system acls = yes

[sysvol]
 path = /var/lib/samba/sysvol
 read only = No
 acl_xattr:ignore system acls = yes




Yours sincerely
