[Samba] [mount.cifs] Mapping Windows ACLs SIDs to POSIX ACL ?

This may sound like a really stupid question, but I could not find any
way to somehow map remote Windows ACLs into POSIX ACLs (mapping users
and group SIDs to Unix mapped ids) when mounting a remote share
(mount.cifs) on a Linux box.
Is is something not currently implemented ? The smbcacls tool can show
the actual ACLs remotely, but this information is not exposed to the
mounted filesystem apparently. The acl feature of the client seem to be
an extension to CIFS allowing to handle POSIX ACLs, not something
allowing a mapping.
Any insightful remark or documentation would be welcome!
[ Note: the only potential issue when mapping would be related to deny
ACLs (AceType == ACCESS_DENIED_ACE_TYPE) ; something which is not
mappable to POSIX ACL. ]
