+ either commas or newlines. An ACL entry is one of the following: </p><pre class="programlisting">
+REVISION:<revision number>
+OWNER:<sid or name>
+GROUP:<sid or name>
+ACL:<sid or name>:<type>/<flags>/<mask>
+</pre><p>The revision of the ACL specifies the internal Windows
+ NT ACL revision for the security descriptor.
+ If not specified it defaults to 1. Using values other than 1 may
+ cause strange behaviour. </p><p>The owner and group specify the owner and group sids for the
+ object. If a SID in the format S-1-x-y-z is specified this is used,
+ otherwise the name specified is resolved using the server on which
+ the file or directory resides. </p><p>ACLs specify permissions granted to the SID. This SID again
+ can be specified in S-1-x-y-z format or as a name in which case
+ it is resolved against the server on which the file or directory
+ resides. The type, flags and mask values determine the type of
+ access granted to the SID. </p><p>The type can be either 0 or 1 corresponding to ALLOWED or
+ DENIED access to the SID. The flags values are generally
+ zero for file ACLs and either 9 or 2 for directory ACLs. Some
+ common flags are: </p><div class="itemizedlist"><ul type="disc"><li><p><code class="constant">#define SEC_ACE_FLAG_OBJECT_INHERIT 0x1</code></p></li><li><p><code class="constant">#define SEC_ACE_FLAG_CONTAINER_INHERIT 0x2</code></p></li><li><p><code class="constant">#define SEC_ACE_FLAG_NO_PROPAGATE_INHERIT 0x4</code></p></li><li><p><code class="constant">#define SEC_ACE_FLAG_INHERIT_ONLY 0x8</code></p></li></ul></div><p>At present flags can only be specified as decimal or
+ hexadecimal values.</p><p>The mask is a value which expresses the access right
+ granted to the SID. It can be given as a decimal or hexadecimal value,
+ or by using one of the following text strings which map to the NT
+ 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'
