>ACL FORMAT</H2
><P
>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: </P
><P
><PRE
CLASS="PROGRAMLISTING"
>
REVISION:<revision number>
OWNER:<sid or name>
GROUP:<sid or name>
ACL:<sid or name>:<type>/<flags>/<mask>
</PRE
></P
><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 CWS-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 CWS-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

granted to the SID. It can be given as a decimal or hexadecimal value,

file permissions of the same name. </P
