README

GoDoc Build Status

Basic LDAP v3 functionality for the GO programming language.

Required Librarys:

  • gopkg.in/asn1-ber.v1

Working:

  • Connecting to LDAP server
  • Binding to LDAP server
  • Searching for entries
  • Compiling string filters to LDAP filters
  • Paging Search Results
  • Modify Requests / Responses

Examples:

  • search
  • modify

Tests Implemented:

  • Filter Compile / Decompile

TODO:

  • Add Requests / Responses
  • Delete Requests / Responses
  • Modify DN Requests / Responses
  • Compare Requests / Responses
  • Implement Tests / Benchmarks

This feature is disabled at the moment, because in some cases the "Search Request Done" packet will be handled before the last "Search Request Entry":

  • Mulitple internal goroutines to handle network traffic Makes library goroutine safe Can perform multiple search requests at the same time and return the results to the proper goroutine. All requests are blocking requests, so the goroutine does not need special handling

Overview

Package ldap provides basic LDAP v3 functionality.

Example (Beherappolicy) 
package main

import (
	"fmt"
	"log"

	"github.com/go-ldap/ldap"
)

func main() {
	l, err := ldap.Dial("tcp", fmt.Sprintf("%s:%d", "ldap.example.com", 389))
	if err != nil {
		log.Fatal(err)
	}
	defer l.Close()

	controls := []ldap.Control{}
	controls = append(controls, ldap.NewControlBeheraPasswordPolicy())
	bindRequest := ldap.NewSimpleBindRequest("cn=admin,dc=example,dc=com", "password", controls)

	r, err := l.SimpleBind(bindRequest)
	ppolicyControl := ldap.FindControl(r.Controls, ldap.ControlTypeBeheraPasswordPolicy)

	var ppolicy *ldap.ControlBeheraPasswordPolicy
	if ppolicyControl != nil {
		ppolicy = ppolicyControl.(*ldap.ControlBeheraPasswordPolicy)
	} else {
		log.Printf("ppolicyControl response not avaliable.\n")
	}
	if err != nil {
		errStr := "ERROR: Cannot bind: " + err.Error()
		if ppolicy != nil && ppolicy.Error >= 0 {
			errStr += ":" + ppolicy.ErrorString
		}
		log.Print(errStr)
	} else {
		logStr := "Login Ok"
		if ppolicy != nil {
			if ppolicy.Expire >= 0 {
				logStr += fmt.Sprintf(". Password expires in %d seconds\n", ppolicy.Expire)
			} else if ppolicy.Grace >= 0 {
				logStr += fmt.Sprintf(". Password expired, %d grace logins remain\n", ppolicy.Grace)
			}
		}
		log.Print(logStr)
	}
}

Example (UserAuthentication)

Example User Authentication shows how a typical application can verify a login attempt 

package main

import (
	"crypto/tls"
	"fmt"
	"log"

	"github.com/go-ldap/ldap"
)

func main() {
	// The username and password we want to check
	username := "someuser"
	password := "userpassword"

	bindusername := "readonly"
	bindpassword := "password"

	l, err := ldap.Dial("tcp", fmt.Sprintf("%s:%d", "ldap.example.com", 389))
	if err != nil {
		log.Fatal(err)
	}
	defer l.Close()

	// Reconnect with TLS
	err = l.StartTLS(&tls.Config{InsecureSkipVerify: true})
	if err != nil {
		log.Fatal(err)
	}

	// First bind with a read only user
	err = l.Bind(bindusername, bindpassword)
	if err != nil {
		log.Fatal(err)
	}

	// Search for the given username
	searchRequest := ldap.NewSearchRequest(
		"dc=example,dc=com",
		ldap.ScopeWholeSubtree, ldap.NeverDerefAliases, 0, 0, false,
		fmt.Sprintf("(&(objectClass=organizationalPerson)&(uid=%s))", username),
		[]string{"dn"},
		nil,
	)

	sr, err := l.Search(searchRequest)
	if err != nil {
		log.Fatal(err)
	}

	if len(sr.Entries) != 1 {
		log.Fatal("User does not exist or too many entries returned")
	}

	userdn := sr.Entries[0].DN

	// Bind as the user to verify their password
	err = l.Bind(userdn, password)
	if err != nil {
		log.Fatal(err)
	}

	// Rebind as the read only user for any futher queries
	err = l.Bind(bindusername, bindpassword)
	if err != nil {
		log.Fatal(err)
	}
}

Example (Vchuppolicy) 
package main

import (

	l.Debug = true

	bindRequest := ldap.NewSimpleBindRequest("cn=admin,dc=example,dc=com", "password", nil)

	r, err := l.SimpleBind(bindRequest)

	passwordMustChangeControl := ldap.FindControl(r.Controls, ldap.ControlTypeVChuPasswordMustChange)
	var passwordMustChange *ldap.ControlVChuPasswordMustChange
	if passwordMustChangeControl != nil {
		passwordMustChange = passwordMustChangeControl.(*ldap.ControlVChuPasswordMustChange)
	}

	if passwordMustChange != nil && passwordMustChange.MustChange {
		log.Printf("Password Must be changed.\n")
	}

	passwordWarningControl := ldap.FindControl(r.Controls, ldap.ControlTypeVChuPasswordWarning)

	var passwordWarning *ldap.ControlVChuPasswordWarning
	if passwordWarningControl != nil {

Functions

func CompileFilter 

func CompileFilter(filter string) (*ber.Packet, error)

func DebugBinaryFile 

func DebugBinaryFile(fileName string) error

func DecompileFilter 

func DecompileFilter(packet *ber.Packet) (ret string, err error)

func EscapeFilter 

func EscapeFilter(filter string) string

EscapeFilter escapes from the provided LDAP filter string the special characters in the set `()*\` and those out of the range 0 < c < 0x80, as defined in RFC4515.

func NewError 

func NewError(resultCode uint8, err error) error

Types

type AttributeTypeAndValue 

type AttributeTypeAndValue struct {
	Type  string
	Value string
}

type Conn 

type Conn struct {
	Debug debugging
	// contains filtered or unexported fields
}

Conn represents an LDAP Connection

func Dial 

func Dial(network, addr string) (*Conn, error)

Dial connects to the given address on the given network using net.Dial and then returns a new Conn for the connection.

func DialTLS 

func DialTLS(network, addr string, config *tls.Config) (*Conn, error)

DialTLS connects to the given address on the given network using tls.Dial and then returns a new Conn for the connection.

func NewConn 

func NewConn(conn net.Conn, isTLS bool) *Conn

NewConn returns a new Conn using conn for network I/O.

func (*Conn) Bind 

func (l *Conn) Bind(username, password string) error
Example

ExampleConn_Bind demonstrats how to bind a connection to an ldap user allowing access to restricted attrabutes that user has access to 

package main

import (
	"fmt"
	"log"

	"github.com/go-ldap/ldap"
)

func main() {
	l, err := ldap.Dial("tcp", fmt.Sprintf("%s:%d", "ldap.example.com", 389))
	if err != nil {
		log.Fatal(err)
	}
	defer l.Close()

	err = l.Bind("cn=read-only-admin,dc=example,dc=com", "password")
	if err != nil {
		log.Fatal(err)
	}
}

Output:

func (*Conn) Close 

func (l *Conn) Close()

Close closes the connection.

func (*Conn) Compare 

func (l *Conn) Compare(dn, attribute, value string) (bool, error)

Compare checks to see if the attribute of the dn matches value. Returns true if it does otherwise false with any error that occurs if any.

Example

ExampleConn_Compare demonstrates how to comapre an attribute with a value 

package main

import (
	"fmt"
	"log"

	"github.com/go-ldap/ldap"
)

func main() {
	l, err := ldap.Dial("tcp", fmt.Sprintf("%s:%d", "ldap.example.com", 389))
	if err != nil {
		log.Fatal(err)
	}
	defer l.Close()

	matched, err := l.Compare("cn=user,dc=example,dc=com", "uid", "someuserid")
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(matched)
}

Output:

func (*Conn) Modify 

func (l *Conn) Modify(modifyRequest *ModifyRequest) error
Example 
package main

import (
	"fmt"
	"log"

	"github.com/go-ldap/ldap"
)

func main() {
	l, err := ldap.Dial("tcp", fmt.Sprintf("%s:%d", "ldap.example.com", 389))
	if err != nil {
		log.Fatal(err)
	}
	defer l.Close()

	// Add a description, and replace the mail attributes
	modify := ldap.NewModifyRequest("cn=user,dc=example,dc=com")
	modify.Add("description", []string{"An example user"})
	modify.Replace("mail", []string{"user@example.org"})

	err = l.Modify(modify)
	if err != nil {
		log.Fatal(err)
	}
}

Output:

func (*Conn) PasswordModify

Create a new PasswordModifyRequest

According to the RFC 3602: userIdentity is a string representing the user associated with the request. This string may or may not be an LDAPDN (RFC 2253). If userIdentity is empty then the operation will act on the user associated with the session.

oldPassword is the current user's password, it can be empty or it can be needed depending on the session user access rights (usually an administrator can change a user's password without knowing the current one) and the password policy (see pwdSafeModify password policy's attribute)

newPassword is the desired user's password. If empty the server can return an error or generate a new password that will be available in the PasswordModifyResult.GeneratedPassword
