Free ldapv3 software for linux

OpenLDAP project is an open-standard protocol for accessing X.500 directory services. The protocol runs over Internet transport protocols, such as TCP.

LDAP is a lightweight alternative to the X.500 Directory Access Protocol (DAP) for use on the Internet. It uses TCP/IP stack verses the overly complex OSI stack. It also has other simplications, such as the representing most attribute values and many protocol items as textual strings, that are designed to make clients easier to implement.

SYNOPSIS

use Net::LDAP;
use Net::LDAP::Control::VLV;
use Net::LDAP::Constant qw( LDAP_CONTROL_VLVRESPONSE );

$ldap = Net::LDAP->new( "ldap.mydomain.eg" );

# Get the first 20 entries
$vlv = Net::LDAP::Control::VLV->new(
before => 0, # No entries from before target entry
after => 19, # 19 entries after target entry
content => 0, # List size unknown
offset => 1, # Target entry is the first
);
$sort = Net::LDAP::Control::Sort->new( order => cn );

@args = ( base => "o=Ace Industry, c=us",
scope => "subtree",
filter => "(objectClass=inetOrgPerson)",
callback => &process_entry, # Call this sub for each entry
control => [ $vlv, $sort ],
);

$mesg = $ldap->search( @args );

# Get VLV response control
($resp) = $mesg->control( LDAP_CONTROL_VLVRESPONSE ) or die;
$vlv->response( $resp );

# Set the control to get the last 20 entries
$vlv->end;

$mesg = $ldap->search( @args );

# Get VLV response control
($resp) = $mesg->control( LDAP_CONTROL_VLVRESPONSE ) or die;
$vlv->response( $resp );

# Now get the previous page
$vlv->scroll_page( -1 );

$mesg = $ldap->search( @args );

# Get VLV response control
($resp) = $mesg->control( LDAP_CONTROL_VLVRESPONSE ) or die;
$vlv->response( $resp );

# Now page with first entry starting with "B" in the middle
$vlv->before(9); # Change page to show 9 before
$vlv->after(10); # Change page to show 10 after
$vlv->assert("B"); # assert "B"

$mesg = $ldap->search( @args );
