109 <title>ACL FORMAT</title>
111 <para>The format of an ACL is one or more ACL entries separated by
112 either commas or newlines. An ACL entry is one of the following: </para>
114 <para><programlisting>
115 REVISION:<revision number>
116 OWNER:<sid or name>
117 GROUP:<sid or name>
118 ACL:<sid or name>:<type>/<flags>/<mask>
119 </programlisting></para>
121 <para>The revision of the ACL specifies the internal Windows
122 NT ACL revision for the security descriptor.
123 If not specified it defaults to 1. Using values other than 1 may
124 cause strange behaviour.</para>
126 <para>The owner and group specify the owner and group SIDs for the
127 object. If a SID in the format S-1-x-y-z is specified this is used,
128 otherwise the name specified is resolved using the server on which
129 the file or directory resides.</para>
131 <para>ACLs specify permissions granted to the SID. This SID
132 can be specified in S-1-x-y-z format or as a name in which case
133 it is resolved against the server on which the file or directory
134 resides. The type, flags and mask values determine the type of
135 access granted to the SID.</para>
137 <para>The type can be either ALLOWED or DENIED to allow/deny access
138 to the SID. The flags values are generally zero for share ACLs.
141 <para>The mask is a value which expresses the access right
142 granted to the SID. It can be given as a decimal or hexadecimal value,
143 or by using one of the following text strings which map to the NT
144 file permissions of the same name.</para>
147 <listitem><para><emphasis>R</emphasis> - Allow read access </para></listitem>
148 <listitem><para><emphasis>W</emphasis> - Allow write access</para></listitem>
149 <listitem><para><emphasis>X</emphasis> - Execute permission on the object</para></listitem>
150 <listitem><para><emphasis>D</emphasis> - Delete the object</para></listitem>
151 <listitem><para><emphasis>P</emphasis> - Change permissions</para></listitem>
152 <listitem><para><emphasis>O</emphasis> - Take ownership</para></listitem>
155 <para>The following combined permissions can be specified:</para>
158 <listitem><para><emphasis>READ</emphasis> - Equivalent to 'RX'
159 permissions</para></listitem>
160 <listitem><para><emphasis>CHANGE</emphasis> - Equivalent to 'RXWD' permissions
162 <listitem><para><emphasis>FULL</emphasis> - Equivalent to 'RWXDPO'
163 permissions</para></listitem>
168 <title>EXIT STATUS</title>
170 <para>The <command>sharesec</command> program sets the exit status
171 depending on the success or otherwise of the operations performed.
172 The exit status may be one of the following values. </para>
174 <para>If the operation succeeded, sharesec returns and exit
175 status of 0. If <command>sharesec</command> couldn't connect to the specified server,
176 or there was an error getting or setting the ACLs, an exit status
177 of 1 is returned. If there was an error parsing any command line
178 arguments, an exit status of 2 is returned. </para>

207 <title>VERSION</title>
209 <para>This man page is correct for version 3 of the Samba suite.</para>
213 <title>AUTHOR</title>
214 <para>The original Samba software and related utilities
215 were created by Andrew Tridgell. Samba is now developed
216 by the Samba Team as an Open Source project similar
217 to the way the Linux kernel is developed.</para>
