Examples

Code overview :

package main

// imports
import (
	"fmt"
	"github.com/mqu/openldap"
)
// initialize
ldap, err := openldap.Initialize(url)

// Options
ldap.SetOption(openldap.LDAP_OPT_PROTOCOL_VERSION, openldap.LDAP_VERSION3)

// authentification
err = ldap.Bind(user, passwd)

// searching
result, err := ldap.**SearchAll**(base, scope, filter, attributes)

// Closing connexion
err = ldap.Close()

Here is an example using opeldap library.

connecting to LDAP server :

• url is server address in format : ldap//host:port/, or ldaps//host:port/

• user and passwd are need for authentification, empty user and passwd allow anonymous access.

  var user, passwd, url, base string

  url = "ldap://some.host:389/" // url = "ldaps://some.host:636/" user = "..." passwd = "..." base = ""

  ldap, err := openldap.Initialize(url)

  if err != nil { fmt.Printf("LDAP::Initialize() : connexion error\n") return }

setup some options

ldap.SetOption(openldap.LDAP_OPT_PROTOCOL_VERSION, openldap.LDAP_VERSION3)

LDAP authentification with Bind() ; allways close connexion when finished.

err = ldap.Bind(user, passwd)
if err != nil {
	fmt.Printf("LDAP::Bind() : bind error\n")
	fmt.Println(err)
	return
}

defer ldap.Close()

Searching LDAP server. SearchAll() is the easiest way to search and read data from LDAP server.

scope := openldap.LDAP_SCOPE_SUBTREE // LDAP_SCOPE_BASE, LDAP_SCOPE_ONELEVEL, LDAP_SCOPE_SUBTREE  
filter := "cn=*admin*"
attributes := []string{"cn", "sn", "givenname", "mail"} // leave empty for all attributes

result, err := ldap.**SearchAll**(base, scope, filter, attributes)

if err != nil {
	fmt.Println(err)
	return
}

Printing search results - lazy way :

fmt.Printf(result)

Printing search results - easy way (same result):

fmt.Printf("# num results : %d\n", result.Count())
fmt.Printf("# search : %s\n", result.Filter())
fmt.Printf("# base : %s\n", result.Base())
fmt.Printf("# attributes : [%s]\n", strings.Join(result.Attributes(), ", "))

for _, entry := range result.Entries() {
	fmt.Printf("dn=%s\n", entry.Dn())
	for _, attr := range entry.Attributes() {
		fmt.Printf("%s=[%s]\n", attr.Name(), strings.Join(attr.Values(), ", "))
	}
	
	fmt.Printf("\n")
}
