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. +</p><p> +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. +</p><p> +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. +</p><p> +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. +</p><p> +Note that only user works in conjunction with the users= list, +so to get the behavior you require, add the line : +</p><pre class="programlisting"> +users = %S +</pre><p> +this is equivalent to: +</p><pre class="programlisting"> +valid users = %S +</pre><p> +to the definition of the [homes] share, as recommended in +the smb.conf man page. +</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2874436"></a>Until a few minutes after samba has started, clients get the error "Domain Controller Unavailable"</h2></div></div><p> +A domain controller has to announce on the network who it is.
