Lanman does not seem to have a password key or value. Run this code:

use Win32::LanMan qw(NetUserGetInfo);

Win32::Lanman::NetUserGetInfo("","Administrator",\%info);

foreach $key (keys %info)
{
    print $key . " = " . $info{$key} . "\n";
}

And you see that the output is:

logon_server = \\*
last_logoff = 0
workstations =
usr_comment =
name = Administrator
parms =
auth_flags = 0
logon_hours =

priv = 2

password_age = 15750588

max_storage = -1

home_dir =
country_code = 0
num_logons = 5
acct_expires = -1
primary_group_id = 513
last_logon = 984601420
password_expired = 0

There is no password field. So, you cannot compare them. I would use the AdminMisc module. It will probably work out better for you.
