+<title>The data on the CD-Drive I've shared seems to be corrupted!</title>
+
+<para>
+Some OSes (notably Linux) default to auto detection of file type on
+cdroms and do cr/lf translation. This is a very bad idea when use with
+Samba. It causes all sorts of stuff ups.
+</para>
+
+<para>
+To overcome this problem use conv=binary when mounting the cdrom
+before exporting it with Samba.

+<title>Why can users access home directories of other users?</title>
+
+<para>
+<quote>
+We are unable to keep individual users from mapping to any other user's
+home directory once they have supplied a valid password! They only need
+to enter their own password. I have not found *any* method that I can
+use to configure samba to enforce that only a user may map their own
+home directory.

+<para><quote>
+User xyzzy can map his home directory. Once mapped user xyzzy can also map
+*anyone* elses home directory!
+</quote></para>

+<para>
+This is not a security flaw, it is by design. Samba allows
+users to have *exactly* the same access to the UNIX filesystem
+as they would if they were logged onto the UNIX box, except
+that it only allows such views onto the file system as are
+allowed by the defined shares.
+</para>
+
+<para>
+This means that if your UNIX home directories are set up
+such that one user can happily cd into another users
+directory and do an ls, the UNIX security solution is to 
+change the UNIX file permissions on the users home directories
+such that the cd and ls would be denied.
+</para>
+
+<para>
+Samba tries very hard not to second guess the UNIX administrators
+security policies, and trusts the UNIX admin to set
+the policies and permissions he or she desires.
+</para>
+
+<para>
+Samba does allow the setup you require when you have set the
+"only user = yes" option on the share, is that you have not set the
+valid users list for the share.
+</para>
+
+<para>
+Note that only user works in conjunction with the users= list,
+so to get the behavior you require, add the line :
+<programlisting>
+users = %S
+</programlisting>
+this is equivalent to:
+<programlisting>
+valid users = %S
+</programlisting>
+to the definition of the [homes] share, as recommended in
+the smb.conf man page.
