attribute named "user.DOSATTRIB". This extended attribute is explicitly hidden from smbd clients requesting an
EA list. On Linux the filesystem must have been mounted with the mount option user_xattr in order for
extended attributes to work, also extended attributes must be compiled into the Linux kernel.
+
+ In Samba 3.5.0 and above the "user.DOSATTRIB" extended attribute has been extended to store
+ the create time for a file as well as the DOS attributes. This is done in a backwards compatible
+ way so files created by Samba 3.5.0 and above can still have the DOS attribute read from this
+ extended attribute by earlier versions of Samba, but they will not be able to read the create
+ time stored there. Storing the create time separately from the normal filesystem meta-data
+ allows Samba to faithfully reproduce NTFS semantics on top of a POSIX filesystem.
