I have two DCs in my Samba AD with sysvol replication via rsync set up to run every 5 minutes.
On the PDC, samba-tool ntacl sysvolcheck returns no errors.
On the BDC, samba-tool ntacl sysvolcheck returns this error:
ERROR(<class ‘samba.provision.ProvisioningError’>): uncaught exception – ProvisioningError: VFS ACL on sysvol directory /var/lib/samba/sysvol/<my domain> O:LAG:BAD:(A;OICI;0x001f01ff;;;LA)(A;OICI;0x001200a9;;;LG)(A;OICI;0x001f01ff;;;BG)(A;OICI;0x001200a9;;;BU)(A;OICI;0x001f01ff;;;BA)(A;OICI;0x001f01ff;;;BA)(A;OICI;0x001200a9;;;LG)(A;OICI;0x001f01ff;;;BG)(A;OICI;0x001200a9;;;BU)(A;;0x001f01ff;;;BA)(A;;0x001f01ff;;;LA)(A;;0x001200a9;;;WD)(A;OICIIO;0x001f01ff;;;CO)(A;OICIIO;;;;CG)(A;OICIIO;;;;WD) does not match expected value O:LAG:BAD:P(A;OICI;0x001f01ff;;;BA)(A;OICI;0x001200a9;;;SO)(A;OICI;0x001f01ff;;;SY)(A;OICI;0x001200a9;;;AU) from provision

raise ProvisioningError(‘%s ACL on sysvol directory %s %s does not match expected value %s from provision’ % (acl_type(direct_db_access), dir_path, fsacl_sddl, SYSVOL_ACL))

I can run sysvolreset on the BDC which fixes the problem, but then after 5 minutes when the rsync job finishes replication the error returns on the BDC once again.
And during all this the PDC still returns no errors. It seems like something going on exclusively on the BDC’s end.
As far as I can see, this isn’t really causing any problems…group policies still work on the domain. Should I just let this go then?
Any help would be appreciated!
