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
• 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

// 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)
}
