Routine Description:

    This routine assumes privilege checking HAS NOT yet been performed
    and so will be performed by this routine.

    This procedure is used to build a security descriptor for a new object
    given the security descriptor of its parent directory and any originally
    requested security for the object.  The final security descriptor
    returned to the caller may contain a mix of information, some explicitly
    provided other from the new object's parent.


    See RtlpNewSecurityObject for a descriptor of how the NewDescriptor is
    built.


Arguments:

    ParentDescriptor - Optionally supplies the security descriptor of the
        parent directory under which this new object is being created.

    ExplicitDescriptor - Supplies the address of a pointer to the security
        descriptor as specified by the user that is to be applied to
        the new object.

    NewDescriptor - Returns the actual security descriptor for the new
        object that has been modified according to above rules.

    IsDirectoryObject - Specifies if the new object is itself a directory
        object.  A value of TRUE indicates the object is a container of other
        objects.

    SubjectContext - Supplies the security context of the subject creating the
        object. This is used to retrieve default security information for the
        new object, such as default owner, primary group, and discretionary
        access control.

    GenericMapping - Supplies a pointer to an array of access mask values
        denoting the mapping between each generic right to non-generic rights.

    PoolType - Specifies the pool type to use to when allocating a new
        security descriptor.

Return Value:

    STATUS_SUCCESS - indicates the operation was successful.

    STATUS_INVALID_OWNER - The owner SID provided as the owner of the
        target security descriptor is not one the caller is authorized
        to assign as the owner of an object.

    STATUS_PRIVILEGE_NOT_HELD - The caller does not have the privilege
        necessary to explicitly assign the specified system ACL.
        SeSecurityPrivilege privilege is needed to explicitly assign
        system ACLs to objects.

    See RtlpNewSecurityObject for a descriptor of how the NewDescriptor is

Arguments:

    ParentDescriptor - Optionally supplies the security descriptor of the
        parent directory under which this new object is being created.

    ExplicitDescriptor - Supplies the address of a pointer to the security
        descriptor as specified by the user that is to be applied to
        the new object.

    NewDescriptor - Returns the actual security descriptor for the new
        object that has been modified according to above rules.

    ObjectType - GUID of the object type being created.  If the object being
        created has no GUID associated with it, then this argument is
        specified as NULL.

    IsDirectoryObject - Specifies if the new object is itself a directory
        object.  A value of TRUE indicates the object is a container of other
        objects.

    AutoInheritFlags - Controls automatic inheritance of ACES from the Parent
        Descriptor.  Valid values are a bits mask of the logical OR of
        one or more of the following bits:

        SEF_DACL_AUTO_INHERIT - If set, inherit ACEs from the
            DACL ParentDescriptor are inherited to NewDescriptor in addition
            to any explicit ACEs specified by the CreatorDescriptor.

        SEF_SACL_AUTO_INHERIT - If set, inherit ACEs from the
            SACL ParentDescriptor are inherited to NewDescriptor in addition
            to any explicit ACEs specified by the CreatorDescriptor.

        SEF_DEFAULT_DESCRIPTOR_FOR_OBJECT - If set, the CreatorDescriptor
            is the default descriptor for ObjectType.  As such, the
            CreatorDescriptor will be ignored if any ObjectType specific
            ACEs are inherited from the parent.  If no such ACEs are inherited,
            the CreatorDescriptor is handled as though this flag were not
            specified.

        SEF_AVOID_PRIVILEGE_CHECK - If set, no privilege checking is done by this
            routine.  This flag is useful while implementing automatic inheritance
            to avoid checking privileges on each child updated.

    SubjectContext - Supplies the security context of the subject creating the
        object. This is used to retrieve default security information for the
        new object, such as default owner, primary group, and discretionary
        access control.

    GenericMapping - Supplies a pointer to an array of access mask values
        denoting the mapping between each generic right to non-generic rights.

    PoolType - Specifies the pool type to use to when allocating a new
        security descriptor.

Return Value:

    STATUS_SUCCESS - indicates the operation was successful.

    STATUS_INVALID_OWNER - The owner SID provided as the owner of the
        target security descriptor is not one the caller is authorized
        to assign as the owner of an object.

    STATUS_PRIVILEGE_NOT_HELD - The caller does not have the privilege
        necessary to explicitly assign the specified system ACL.
        SeSecurityPrivilege privilege is needed to explicitly assign
        system ACLs to objects.
