I am using some .NET assembly with OLE method. Method in .NET looks like this: 
public int IdentifyUserByCert(string certB64, ref string userTaxId, re
+f string corpTaxId)

[download]
Calling it from C# looks like this 
DefaultCertUserIdentification identi = new DefaultCertUserIdentificati
+on(new Configuration());
string userTaxNum = "";
string corpTaxNum = "";

identi.IdentifyUserByCert(TestData.ACNLB_FO2, ref userTaxNum, ref corp
+TaxNum);

[download]
After this call in variable userTaxNum, and corpTaxNum there are some return values. In Perl I am using same assembly via OLE like this. 
my $identi = Win32::OLE->new('DefaultCertUserIdentification');

my $identified = $identi->IdentifyUserByCert($certificate, \$userTaxId
+, \$corpTaxId);

[download]
Return valu is OK. It works as expected. I was expecting to get values in $userTaxId, and $corpTaxId, but I do not.
