37 either commas or newlines. An ACL entry is one of the following: </p><pre class="programlisting">
38 REVISION:&lt;revision number&gt;
39 OWNER:&lt;sid or name&gt;
40 GROUP:&lt;sid or name&gt;
41 ACL:&lt;sid or name&gt;:&lt;type&gt;/&lt;flags&gt;/&lt;mask&gt;
42 </pre><p>The revision of the ACL specifies the internal Windows
43 NT ACL revision for the security descriptor.
44 If not specified it defaults to 1. Using values other than 1 may
45 cause strange behaviour.</p><p>The owner and group specify the owner and group SIDs for the
46 object. If a SID in the format S-1-x-y-z is specified this is used,
47 otherwise the name specified is resolved using the server on which
48 the file or directory resides.</p><p>ACLs specify permissions granted to the SID. This SID
49 can be specified in S-1-x-y-z format or as a name in which case
50 it is resolved against the server on which the file or directory
51 resides. The type, flags and mask values determine the type of
52 access granted to the SID.</p><p>The type can be either ALLOWED or DENIED to allow/deny access
53 to the SID. The flags values are generally zero for share ACLs.
54 </p><p>The mask is a value which expresses the access right
55 granted to the SID. It can be given as a decimal or hexadecimal value,
56 or by using one of the following text strings which map to the NT
57 file permissions of the same name.</p><div class="itemizedlist"><ul type="disc"><li><p><span class="emphasis"><em>R</em></span> - Allow read access </p></li><li><p><span class="emphasis"><em>W</em></span> - Allow write access</p></li><li><p><span class="emphasis"><em>X</em></span> - Execute permission on the object</p></li><li><p><span class="emphasis"><em>D</em></span> - Delete the object</p></li><li><p><span class="emphasis"><em>P</em></span> - Change permissions</p></li><li><p><span class="emphasis"><em>O</em></span> - Take ownership</p></li></ul></div><p>The following combined permissions can be specified:</p><div class="itemizedlist"><ul type="disc"><li><p><span class="emphasis"><em>READ</em></span> - Equivalent to 'RX'

61 depending on the success or otherwise of the operations performed.
62 The exit status may be one of the following values. </p><p>If the operation succeeded, sharesec returns and exit
63 status of 0. If <code class="literal">sharesec</code> couldn't connect to the specified server,
64 or there was an error getting or setting the ACLs, an exit status
65 of 1 is returned. If there was an error parsing any command line
66 arguments, an exit status of 2 is returned. </p></div><div class="refsect1" lang="en"><a name="id2481696"></a><h2>EXAMPLES</h2><p>Add full access for SID
