Eiffel

Eiffel does not have the notion of "return", but "Result". A consequence of this is that Eiffel routines are Single-entry-Single-exit, which means less bugs. In the example (below), the Result is of type BOOLEAN.

Moreover, strings in Eiffel are objects and cannot be directly passed to the Windows OS. As such, they need to undergo a format change through the facilities of a WEL_STRING, which makes the appropriate structure conversion.


feature -- Validation

	is_user_credential_valid (a_domain, a_username, a_password: READABLE_STRING_GENERAL): BOOLEAN
			-- Is the pair `a_username'/`a_password' a valid credential in `a_domain'?
		local
			l_domain, l_username, l_password: WEL_STRING
		do
			create l_domain.make (a_domain)
			create l_username.make (a_username)
			create l_password.make (a_password)
			Result := cwel_is_credential_valid (l_domain.item, l_username.item, l_password.item)
		end

Because Active Directory is a Windows OS facility, in Eiffel we must use the WEL (Windows Eiffel Library) components. Thus, the code above is not cross-platform. Moreover, the call to `cwel_is_credential_valid' is shown below:


	cwel_is_credential_valid (a_domain, a_username, a_password: POINTER): BOOLEAN
		external
			"C inline use %"wel_user_validation.h%""
		alias
			"return cwel_is_credential_valid ((LPTSTR) $a_domain, (LPTSTR) $a_username, (LPTSTR) $a_password);"
		end

Go

{{libheader|go-ldap-client}}

There are a large number of third-party LDAP libraries for Go. This uses one of the simpler ones and the code below is largely taken from the example on its main page.

package main

import (
    "log"
    "github.com/jtblin/go-ldap-client"
)

func main() {
    client := &ldap.LDAPClient{
        Base:        "dc=example,dc=com",
        Host:        "ldap.example.com",
        Port:        389,
        GroupFilter: "(memberUid=%s)",
    }
    defer client.Close()
    err := client.Connect()
    if err != nil { 
        log.Fatalf("Failed to connect : %+v", err)
    }
    groups, err := client.GetGroupsOfUser("username")
    if err != nil {
        log.Fatalf("Error getting groups for user %s: %+v", "username", err)
    }
    log.Printf("Groups: %+v", groups) 
}

Haskell

Example uses the [https://hackage.haskell.org/package/ldap-client ldap-client] package:

{-# LANGUAGE OverloadedStrings #-}

module Main (main) where

import           Data.Foldable (for_)
import qualified Data.Text.Encoding as Text (encodeUtf8)
import           Ldap.Client (Attr(..), Filter(..))
import qualified Ldap.Client as Ldap (Dn(..), Host(..), search, with, typesOnly)

main :: IO ()
main = do
    entries <- Ldap.with (Ldap.Plain "localhost") 389 $ \ldap ->
        Ldap.search ldap (Ldap.Dn "o=example.com") (Ldap.typesOnly True) (Attr "uid" := Text.encodeUtf8 "user") []
    for_ entries $ \entry ->
        print entry

Tcl

One can do it with the low level [[Connect to Active Directory]] based handle with this code:

This is just the basic setup.

set Username "TestUser"
set Filter "((&objectClass=*)(sAMAccountName=$Username))"
set Base "dc=skycityauckland,dc=sceg,dc=com"
set Attrs distinguishedName

Now do the actual search.

set result [ldap::search $conn $Base $Filter $Attrs -scope subtree]

If we have only a single result its easy:

if {[llength $result] == 1} {
    puts [dict get [lindex $result 0 1] distinguishedName]
}

Looping over the result set to output some values.

foreach pair $result {
    lassign $pair cn attributes
    puts [dict get $attributes distinguishedName]
}

If you're bored you can also use this instead:

package require ldapx
set conn [ldapx::connect $BindDN $Password]
$conn traverse $Base $Filter $Attrs e {
    puts [$e get distinguishedName]
}

UNIX Shell

Using LDAP connecting to a local [http://directory.apache.org/apacheds/1.5/ ApacheDS] LDAP directory server.

A shell script to drive the ldapsearch command.

#!/bin/sh

LDAP_HOST="localhost"
LDAP_PORT=11389
LDAP_DN_STR="uid=admin,ou=system"
LDAP_CREDS="********"
LDAP_BASE_DN="ou=users,o=mojo"
LDAP_SCOPE="sub"
LDAP_FILTER="(&(objectClass=person)(&(uid=*mil*)))"
LDAP_ATTRIBUTES="dn cn sn uid"

ldapsearch \
  -s base \
  -h $LDAP_HOST \
  -p $LDAP_PORT \
  -LLL \
  -x \
  -v \
  -s $LDAP_SCOPE \
  -D $LDAP_DN_STR \
  -w $LDAP_CREDS \
  -b $LDAP_BASE_DN \
  $LDAP_FILTER \
  $LDAP_ATTRIBUTES

'''Output:'''


ldap_initialize( ldap://localhost:11389 )
filter: (&(objectClass=person)(&(uid=*mil*)))
requesting: dn cn sn uid 
dn: cn=John Milton,ou=users,o=mojo
uid: jmilton
sn: Milton
cn: John Milton

VBScript

The search string and execution of the string

strUsername = "TestUser"
strQuery = "<LDAP://dc=skycityauckland,dc=sceg,dc=com>;"_
 & "(&(objectclass=*)(samaccountname=" & strUsername & "));distinguishedname;subtree"
objCmd.ActiveConnection = objConn
objCmd.Properties("Page Size")=100
objCmd.CommandText = strQuery
Set objRS = objCmd.Execute

Doing something with a single result (this will output the returned users full DN)

If objRS.RecordCount = 1 Then
  WScript.Echo objRS.Fields("DistinguishedName")
End If

Doing something with multiple results (this will output each returned users full DN)

 0 Then
  For Each objUser in ObjRS
    WScript.Echo objRS.Fields("DistinguishedName")
  Next
End If
