Want to fetch MS Exchange attributes in Perl-Linux

I am using Perl in Linux Environment. want to fetch MS Exchange attributes (like mAPIRecipient) Using Net::LDAPS, but it only gives me access t开发者_开发问答o LDAP attributes (not Exchange attr.) In Windows it seems possible with Win32::OLE How can we do it in perl ?

I don't see why Net::LDAP would not give you all the attributes, included the Active Directory ones, as it does not discern between LDAP and AD/MS Exchange attributes.

Just ran this code in one of our Linux servers:

   use v5.10;
   use Net::LDAP;
   my $filter = '(&(objectCategory=user))';
   my $base   = 'dc=example,dc=com';
   my $ldap = Net::LDAP->new( $host ) or die $!;
   my $ldap->bind('myuser', password=>'s3cr3t' );
   my $results = $ldap->search( 
          base   => $base, 
          scope  =>'sub', 
          filter =>$filter 
   );
   # to detect bind/search errors:
   die $results->error if $results->code; 
   my $entry = $results->entry(0);
   say for sort $entry->attributes; 

These are the attributes I got from our AD. I don't see mAPIRecipient, maybe because it's not configured to come out, not sure, but I get a lot of other MS Exchange specifics:
