| 7 | If this parameter is set Samba attempts to first read DOS attributes (SYSTEM, HIDDEN, ARCHIVE or
|
|---|
| 8 | READ-ONLY) from a filesystem extended attribute, before mapping DOS attributes to UNIX permission bits (such
|
|---|
| 9 | as occurs with <smbconfoption name="map hidden"/> and <smbconfoption name="map readonly"/>). When set, DOS
|
|---|
| 10 | attributes will be stored onto an extended attribute in the UNIX filesystem, associated with the file or
|
|---|
| 11 | directory. For no other mapping to occur as a fall-back, the parameters <smbconfoption name="map hidden"/>,
|
|---|
| 12 | <smbconfoption name="map system"/>, <smbconfoption name="map archive"/> and <smbconfoption name="map
|
|---|
| 13 | readonly"/> must be set to off. This parameter writes the DOS attributes as a string into the extended
|
|---|
| 14 | attribute named "user.DOSATTRIB". This extended attribute is explicitly hidden from smbd clients requesting an
|
|---|
| 15 | EA list. On Linux the filesystem must have been mounted with the mount option user_xattr in order for
|
|---|
| 16 | extended attributes to work, also extended attributes must be compiled into the Linux kernel.
|
|---|
| 17 |
|
|---|
| 18 | In Samba 3.5.0 and above the "user.DOSATTRIB" extended attribute has been extended to store
|
|---|
| 19 | the create time for a file as well as the DOS attributes. This is done in a backwards compatible
|
|---|
| 20 | way so files created by Samba 3.5.0 and above can still have the DOS attribute read from this
|
|---|
| 21 | extended attribute by earlier versions of Samba, but they will not be able to read the create
|
|---|
| 22 | time stored there. Storing the create time separately from the normal filesystem meta-data
|
|---|
| 23 | allows Samba to faithfully reproduce NTFS semantics on top of a POSIX filesystem.
