+ <title>DESCRIPTION</title>
+
+ <para>This VFS module is part of the
+ <citerefentry><refentrytitle>samba</refentrytitle>
+ <manvolnum>7</manvolnum></citerefentry> suite.</para>
+
+ <para>The <command>vfs_streams_xattr</command> enables storing of NTFS
+ alternate data streams in the file system. As a normal posix file
+ system does not support the concept of multiple data streams per file,
+ the streams_xattr module stores the data in posix extended attributes
+ (xattrs). The name of these attributes by default is
+ user.DosStream."ADS-NAME". The prefix "user.DosStream." can be changed
+ with the module option <command>streams_xattr:prefix</command>, but be
+ aware that this will also expose those ADS over the SMB extended
+ attributes interface.</para>
+
+ <para>The file system that is shared with this module enabled must
+ support xattrs.</para>
+
+ <para>Please note that most file systems have severe limitations on
+ the size of xattrs. So this module might work for applications like IE
+ that stores small zone information in streams but will fail for
+ applications that store serious amounts of data in ADSs.</para>
