[rt-users] modifing users

[victor]

I want to do same export from a software that I use into rt.
New users and disable users work.
Now I want to modify users in rt when I modify a user in the other software.
But I can't make get the UpdateRecordObject to work.

I do like this:
use lib "/opt/rt3/lib";
use strict;
use English;
use RT::Interface::Web qw(UpdateRecordObject);
use RT::User;
RT::LoadConfig();
RT::Init();
my $UserObj = RT::User->new(RT::SystemUser);
$UserObj->LoadByEmail('cynet5 at ambra.ro');
my @fields = qw(Name);
my %ARGS;
$ARGS{'Name'} = 'New value';
UpdateRecordObject(AttributesRef => \@fields,
                   Object => $UserObj,
                   ARGSRef => \%ARGS
                   );

But the erorr is :
[Tue Nov  4 09:50:08 2003] [crit]: Undefined subroutine
&main::UpdateRecordObject called at ./rt.modify line 27.
 (/opt/rt3/lib/RT.pm:242)


Thank you
