A flaw was found in samba. A newly delegated right, but more importantly the removal of a delegated right, would not be inherited on any DC other than the one where the change was made; the removal would not automatically be taken away on all domain controllers. The highest threat from this vulnerability is to data confidentiality and integrity.
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.
