hey ppl

i m trying to authenticate with rlm_perl using chap with following perl script but doesn't seem to work. i m guessing chap-password should be in hex (0x) format but doesn't seem to be in. hope some one can help me out
Best Regards
my $want_password="123";my $given_password;my $given_chap_challenge;

$given_password =~ s/^0x//;$given_chap_challenge =~ s/^0x//;my $chap_password = pack("H*", $given_password);my $chap_challenge = pack("H*", $given_chap_challenge);my $md5 = new Digest::MD5;
$md5->reset;$md5->add(substr($chap_password, 0, 1));$md5->add($want_password);$md5->add($chap_challenge);
my $digest = $md5->digest();my $subby = substr($chap_password,1);my $subby2 = substr($chap_password,0,1);if ($digest ne substr($chap_password, 1)) {#return 0; #Bad pass returning 0
$RAD_REPLY{'Reply-Message'} = "Denied access for  invalid password";}
}else {#return 1; # Pass is OK Returning 1
return RLM_MODULE_OK;}
