**This package is a work in progress.**

**ldapserver** is a helper library for building server software capable of speaking the LDAP protocol. This could be an alternate implementation of LDAP, a custom LDAP proxy or even a completely different backend capable of "masquerading" its API as a LDAP Server.

The package supports 

* All basic LDAP Operations (bind, search, add, compare, modify, delete, extended)

* SSL

* StartTLS

* Unbind request is implemented, but is handled internally to close the connection.

* Graceful stopping

* Basic request routing inspired by [net/http ServeMux](http://golang.org/pkg/net/http/#ServeMux)

* Logger customisation (log interface)

# Default behaviors

## Abandon request

If you don't set a route to handle AbandonRequest, the package will handle it for you. (signal sent to message.Done chan)

## No Route Found

When no route matches the request, the server will first try to call a special *NotFound* route, if nothing is specified, it will return an *UnwillingToResponse* Error code (53)

Feel free to contribute, comment :)

#  Sample Code

```Go

// Listen to 10389 port for LDAP Request

// and route bind request to the handleBind func

package main

import (

	"log"

	"os"

	"os/signal"

	"syscall"

	ldap "github.com/vjeantet/ldapserver"

)

func main() {

	//ldap logger

	ldap.Logger = log.New(os.Stdout, "[server] ", log.LstdFlags)

	//Create a new LDAP Server

	server := ldap.NewServer()

	routes := ldap.NewRouteMux()

	routes.Bind(handleBind)

	server.Handle(routes)

	// listen on 10389

	go server.ListenAndServe("127.0.0.1:10389")

	// When CTRL+C, SIGINT and SIGTERM signal occurs

	// Then stop server gracefully

	ch := make(chan os.Signal)

	signal.Notify(ch, syscall.SIGINT, syscall.SIGTERM)

	<-ch

	close(ch)

	server.Stop()

}

// handleBind return Success if login == mysql

func handleBind(w ldap.ResponseWriter, m *ldap.Message) {

	r := m.GetBindRequest()

	res := ldap.NewBindResponse(ldap.LDAPResultSuccess)

	if string(r.Name()) == "myLogin" {

		w.Write(res)

		return

	}

	log.Printf("Bind failed User=%s, Pass=%s", string(r.Name()), string(r.AuthenticationSimple()))

	res.SetResultCode(ldap.LDAPResultInvalidCredentials)

	res.SetDiagnosticMessage("invalid credentials")

	w.Write(res)

}

```
