# 389, 636, 3268, 3269 - LDAP

**Default ports:** 389 and 636(ldaps). Global Catalog (LDAP in ActiveDirectory) is available by default on ports 3268, and 3269 for LDAPS.

```
PORT    STATE SERVICE REASON
389/tcp open  ldap    syn-ack
636/tcp open  tcpwrapped
```

Get public information (like the domain name):

```bash
nmap -n -sV --script "ldap* and not brute" <IP> #Using anonymous credentials
```

## <mark style="color:red;">Ldapsearch</mark>

Check null credentials or if your credentials are valid:

```bash
ldapsearch -x -H ldap://<IP> -D '' -w '' -b "DC=<1_SUBDOMAIN>,DC=<TLD>"
ldapsearch -h <IP> -bx "DC=<SUBDOMAIN>,DC=<TLD>"
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "DC=<1_SUBDOMAIN>,DC=<TLD>"
```

```bash
# CREDENTIALS NOT VALID RESPONSE
search: 2
result: 1 Operations error
text: 000004DC: LdapErr: DSID-0C090A4C, comment: In order to perform this opera
 tion a successful bind must be completed on the connection., data 0, v3839
```

If you find something saying that the "*bind must be completed*" means that the credentials are incorrect.

You can extract **everything from a domain** using:

```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "DC=<1_SUBDOMAIN>,DC=<TLD>"
-x Simple Authentication
-H LDAP Server
-D My User
-w My password
-b Base site, all data from here will be given
```

Extract **users**:

```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Users,DC=<1_SUBDOMAIN>,DC=<TLD>"
#Example: ldapsearch -x -H ldap://<IP> -D 'MYDOM\john' -w 'johnpassw' -b "CN=Users,DC=mydom,DC=local"
```

Extract **computers**:

```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Computers,DC=<1_SUBDOMAIN>,DC=<TLD>"
```

Extract **my info**:

```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=<MY NAME>,CN=Users,DC=<1_SUBDOMAIN>,DC=<TLD>"
```

Extract **Domain Admins**:

```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Domain Admins,CN=Users,DC=<1_SUBDOMAIN>,DC=<TLD>"
```

Extract **Domain Users**:

```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Domain Users,CN=Users,DC=<1_SUBDOMAIN>,DC=<TLD>"
```

Extract **Enterprise Admins**:

```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Enterprise Admins,CN=Users,DC=<1_SUBDOMAIN>,DC=<TLD>"
```

Extract **Administrators**:

```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Administrators,CN=Builtin,DC=<1_SUBDOMAIN>,DC=<TLD>"
```

Extract **Remote Desktop Group**:

```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Remote Desktop Users,CN=Builtin,DC=<1_SUBDOMAIN>,DC=<TLD>"
```

To see if you have access to any password you can use grep after executing one of the queries:

```bash
<ldapsearchcmd...> | grep -i -A2 -B2 "userpas"
```

Please, notice that the passwords that you can find here could not be the real ones...

## <mark style="color:red;">LDAP enumeration with Python</mark>

You can try to **enumerate a LDAP with or without credentials using python**: `pip3 install ldap3`

First try to **connect without** credentials:

```bash
>>> import ldap3
>>> server = ldap3.Server('x.X.x.X', get_info = ldap3.ALL, port =636, use_ssl = True)
>>> connection = ldap3.Connection(server)
>>> connection.bind()
True
>>> server.info
```

If the response is `True` like in the previous example, you can obtain some **interesting data** of the LDAP (like the **naming context** or **domain name**) server from:

```bash
>>> server.info
DSA info (from DSE):
Supported LDAP versions: 3
Naming contexts: 
dc=DOMAIN,dc=DOMAIN
```

Once you have the naming context you can make some more exciting queries. This simply query should show you all the objects in the directory:

```bash
>>> connection.search(search_base='DC=DOMAIN,DC=DOMAIN', search_filter='(&(objectClass=*))', search_scope='SUBTREE', attributes='*')
True
>> connection.entries
```

Or **dump** the whole ldap:

```bash
>> connection.search(search_base='DC=DOMAIN,DC=DOMAIN', search_filter='(&(objectClass=person))', search_scope='SUBTREE', attributes='userPassword')
True
>>> connection.entries
```
