LDIF use

[Bouarich, R. <Red...@co...>]

Hello everyone,
I'm trying to update my DIT using an LDIF operation:
i'mn doing like the following: 

 $ldif = Net::LDAP::LDIF->new("/usr/reda/LDIF/change.ldif", "w" );
  while( $entry = $ldif->write() ) {
         print " \n\n EN COURS EN COURS EN COURS EN COURS \n\n";
  }
  $ldif->done();

but it doesn't seem to work, i have the following error message:

Can't locate object method "dn" via package "ENTRIES" at
lib/Net/LDAP/LDIF.pm line 167

Can someone help me?

Thanks a lot.
