SYNOPSIS

 use Net::LDAP;
 use Net::LDAP::Control::PreRead;
 use Net::LDAP::Constant qw( LDAP_CONTROL_PREREAD LDAP_SUCCESS );
 $ldap = Net::LDAP->new( "ldap.mydomain.eg" );
 $preread = Net::LDAP::Control::Paged->new( attrs => [ qw/givenName/ ] );
 my $mesg = $ldap->modify( "cn=Barbara Jensen, o=University of Michigan, c=US",
                           replace => { givenName => "Babs" },
                           control => $preread );
 if ($mesg->code eq LDAP_SUCCESS) {
   my ($previous) = $mesg->control( LDAP_CONTROL_PREREAD );
   my $entry = $previous ? $previous->entry() : undef;
   if ($entry) {
     print "givenName changed from '" .
           join("', '", $entry->get_value(givenName") .
           "' to 'Babs'\n");
   }
 }

DESCRIPTION

Net::LDAP::Control::PreRead provides an interface for the creation and manipulation of objects that represent the Pre-Read Control as described by RFC 4527.

CONSTRUCTOR ARGUMENTS

In addition to the constructor arguments described in the Net::LDAP::Control manpage the following are provided.

attrs => [ ATTR, ... ]
A list of attributes to be returned in the entry returned in the response control.

If absent, all attributes are returned.

Operational attributes may be included in the list by explicitely asking for them or by using special "+" feature (provided the server supports this feature).

METHODS

As with the Net::LDAP::Control manpage each constructor argument described above is also avaliable as a method on the object which will return the current value for the attribute if called without an argument, and set a new value for the attribute if called with an argument.

In addition to these methods, the control also supports the following method:

entry ()
Returns the entry from the response control in the response message to the LDAP request that contained the request control.

The result is either a Net::LDAP::Entry object or undefined.
