When a new user is added to the ACL that ACE is inherited correctly in any newly created descendent sub directories but is listed in the windows ACL in those descendents as being inherited from 'None' as opposed to the name of it's parent directory. Example: Create Samba share \\Storage1\WinShare - /mnt/WinShare Set some standard windows permissions in the root ACL of this share Add a sub-directory \\Storage1\WinShare\Test Add ACE on \\Storage1\WinShare\Test for User1 Add a new sub-directory \\Storage1\WinShare\Test\NewFolder Examine ACL for \\Storage1\WinShare\Test\NewFolder ACE for User1 lists 'Inherited from' as None', it should list inherited from as \\Storage1\WinShare\Test Environment: Windows 8 Scientific Linux 6.3 fstab options: acl,user_xattr smb.conf options inherit acls = Yes map acl inherit = Yes cups options = raw store dos attributes = Yes vfs objects = acl_xattr
