	<title>ACL FORMAT</title>

	<para>The format of an ACL is one or more ACL entries separated by
	either commas or newlines.  An ACL entry is one of the following: </para>

	<para><programlisting>
	REVISION:&lt;revision number&gt;
	OWNER:&lt;sid or name&gt;
	GROUP:&lt;sid or name&gt;
	ACL:&lt;sid or name&gt;:&lt;type&gt;/&lt;flags&gt;/&lt;mask&gt;
	</programlisting></para>

	<para>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.</para>

	<para>The owner and group specify the owner and group SIDs for
	the object. Share ACLs do not specify an owner or a group, so
	these fields are empty.</para>

	<para>ACLs specify permissions granted to the SID. This SID
	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.</para>

	<para>The type can be either ALLOWED or	DENIED to allow/deny access
	to the SID. The flags values are generally zero for share ACLs.
	</para>

	<para>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.</para>

	<itemizedlist>
		<listitem><para><emphasis>R</emphasis> - Allow read access </para></listitem>
		<listitem><para><emphasis>W</emphasis> - Allow write access</para></listitem>
		<listitem><para><emphasis>X</emphasis> - Execute permission on the object</para></listitem>
		<listitem><para><emphasis>D</emphasis> - Delete the object</para></listitem>
		<listitem><para><emphasis>P</emphasis> - Change permissions</para></listitem>
		<listitem><para><emphasis>O</emphasis> - Take ownership</para></listitem>
	</itemizedlist>

	<para>The following combined permissions can be specified:</para>

	<itemizedlist>
		<listitem><para><emphasis>READ</emphasis> -  Equivalent to 'RX'
		permissions</para></listitem>
		<listitem><para><emphasis>CHANGE</emphasis> - Equivalent to 'RXWD' permissions
		</para></listitem>
		<listitem><para><emphasis>FULL</emphasis> - Equivalent to 'RWXDPO'
		permissions</para></listitem>
	</itemizedlist>
	</refsect1>

<refsect1>
	<title>EXIT STATUS</title>

	<para>The <command>sharesec</command> program sets the exit status
	depending on the success or otherwise of the operations performed.
	The exit status may be one of the following values. </para>

	<para>If the operation succeeded, sharesec returns and exit
	status of 0.  If <command>sharesec</command> couldn't connect to the specified server,
	or there was an error getting or setting the ACLs, an exit status
	of 1 is returned.  If there was an error parsing any command line
	arguments, an exit status of 2 is returned. </para>
</refsect1>
