Remediation
Red Hat statement
This flaw does not affect the version of samba shipped with Red Hat Enterprise Linux because there is no support for samba as Active Directory Domain Controller.
Red Hat mitigation
Use of 'samba-tool drs replicate $DC1 $DC2 $NC --full-sync' will cause all ACLs to be syncronised from DC2 to DC1, for the given NC (naming context), eg: samba-tool drs replicate my-DC1 my-DC2 DC=samba,DC=example,DC=com --full-sync samba-tool drs replicate my-DC1 my-DC2 CN=Configuration,DC=samba,DC=example,DC=com --full-sync samba-tool drs replicate my-DC2 my-DC1 DC=samba,DC=example,DC=com --full-sync samba-tool drs replicate my-DC2 my-DC1 CN=Configuration,DC=samba,DC=example,DC=com --full-sync Internally both in patched and un-patched versions, for every object replicated with a --full-sync, the inheritance will be correctly calculated. This only needs to be done TO each DC, not for each pair-wise pair.
