 140         <title>ACL FORMAT</title>
 141
 142         <para>The format of an ACL is one or more ACL entries separated by
 143         either commas or newlines.  An ACL entry is one of the following: </para>
 144
 145         <para><programlisting>
 146         REVISION:&lt;revision number&gt;
 147         OWNER:&lt;sid or name&gt;
 148         GROUP:&lt;sid or name&gt;
 149         ACL:&lt;sid or name&gt;:&lt;type&gt;/&lt;flags&gt;/&lt;mask&gt;
 150         </programlisting></para>
 151
 152         <para>The revision of the ACL specifies the internal Windows
 153         NT ACL revision for the security descriptor.
 154         If not specified it defaults to 1. Using values other than 1 may
 155         cause strange behaviour.</para>
 156
 157         <para>The owner and group specify the owner and group SIDs for the
 158         object. If a SID in the format S-1-x-y-z is specified this is used,
 159         otherwise the name specified is resolved using the server on which
 160         the file or directory resides.</para>
 161
 162         <para>ACLs specify permissions granted to the SID. This SID
 163         can be specified in S-1-x-y-z format or as a name in which case
 164         it is resolved against the server on which the file or directory
 165         resides.  The type, flags and mask values determine the type of
 166         access granted to the SID.</para>
 167
 168         <para>The type can be either ALLOWED or DENIED to allow/deny access
 169         to the SID. The flags values are generally zero for share ACLs.
 170         </para>
 171
 172         <para>The mask is a value which expresses the access right
 173         granted to the SID. It can be given as a decimal or hexadecimal value,
 174         or by using one of the following text strings which map to the NT
 175         file permissions of the same name.</para>
