SYNOPSIS
package MyServer;
use Net::LDAP::Server;
use Net::LDAP::Constant qw(LDAP_SUCCESS);
use base 'Net::LDAP::Server';
sub search {
my $self = shift;
my ($reqData, $fullRequest) = @_;
print "Searching\n";
...
return {
'matchedDN' => '',
'errorMessage' => '',
'resultCode' => LDAP_SUCCESS
}, @entries;
}
package main; my $handler = MyServer->new($socket); $handler->handle;
ABSTRACT
This class provides the protocol handling for an LDAP server. You can subclass it and implement the methods you need (see below). Then you just instantiate your subclass and call its "handle" method to establish a connection with the client.SUBCLASSING
You can subclass Net::LDAP::Server with the following lines:
package MyServer; use Net::LDAP::Server; use base 'Net::LDAP::Server';
Then you can add your custom methods by just implementing a subroutine named after the name of each method. These are supported methods:
For any method that is not supplied, Net::LDAP::Server will return an
"LDAP_UNWILLING_TO_PERFORM".
new()
You can also subclass the "new" constructor to do something at connection time:
sub new {
my ($class, $sock) = @_;
my $self = $class->SUPER::new($sock);
printf "Accepted connection from: %s\n", $sock->peerhost();
return $self;
}
Note that $self is constructed using the fields pragma, so if you want to add data to it you should add a line like this in your subclass:
use fields qw(myCustomField1 myCustomField2);
Methods
When a method is invoked it will be obviously passed $self as generated by "new", and two variables:
- * the Request datastructure that is specific for this method (e.g. BindRequest);
- * the full request message (useful if you want to access messageID or controls parts)
You can look at Net::LDAP::ASN or use Data::Dumper to find out what is presented to your method:
use Data::Dumper;
sub search {
print Dumper \@_;
}
If anything goes wrong in the module you specify (e.g. it died or the result is not a correct ldapresult structure) Net::LDAP::Server will return an "LDAP_OPERATIONS_ERROR" where the errorMessage will specify what went wrong.
All methods should return a LDAPresult hashref, for example:
return({
'matchedDN' => '',
'errorMessage' => '',
'resultCode' => LDAP_SUCCESS
});
"search" should return a LDAPresult hashref followed by a list of entries (if applicable). Entries may be coded either as searchResEntry or searchRefEntry structures or as Net::LDAP::Entry or Net::LDAP::Reference objects.
CLIENT HANDLING
handle()
When you get a socket from a client you can instantiate the class and handle the request:
my $handler = MyServer->new($socket); $handler->handle;
See examples in examples/ directory for sample servers, using IO::Select or Net::Daemon.
