title: Create an LDAP provider
---

### Create Service account

1. Create a new user account to bind with under _Directory_ -> _Users_ -> _Create_, in this example called `ldapservice`.

    Note the DN of this user will be `cn=ldapservice,ou=users,dc=ldap,dc=goauthentik,dc=io`

:::info
Note: The `default-authentication-flow` validates MFA by default, and currently everything but SMS-based devices and WebAuthn devices are supported by LDAP. If you plan to use only dedicated service accounts to bind to LDAP, or don't use SMS-based authenticators, then you can use the default flow and skip the extra steps below and continue at [Create LDAP Application & Provider](#create-ldap-application--provider)
:::

### LDAP Flow

#### Create Custom Stages

1. Create a new identification stage. _Flows & Stage_ -> _Stages_ -> _Create_
   ![](./general_setup1.png)
2. Name it `ldap-identification-stage`. Select User fields Username and Email (and UPN if it is relevant to your setup).
   ![](./general_setup2.png)
3. Create a new password stage. _Flows & Stage_ -> _Stages_ -> _Create_
   ![](./general_setup3.png)
4. Name it `ldap-authentication-password`. Leave the defaults for Backends.

5. Create a new user login stage. _Flows & Stage_ -> _Stages_ -> _Create_
   ![](./general_setup5.png)
6. Name it `ldap-authentication-login`.
   ![](./general_setup6.png)

#### Create Custom Flow

1. Create a new authentication flow under _Flows & Stage_ -> _Flows_ -> _Create_, and name it `ldap-authentication-flow`
   ![](./general_setup7.png)
2. Click the newly created flow and choose _Stage Bindings_.
   ![](./general_setup8.png)
3. Click `Bind Stage` choose `ldap-identification-stage` and set the order to `10`.
   ![](./general_setup9.png)
4. Click `Bind Stage` choose `ldap-authentication-login` and set the order to `30`.
   ![](./general_setup11.png)
5. Edit the `ldap-identification-stage`.
   ![](./general_setup12.png)
6. Change the Password stage to `ldap-authentication-password`.
   ![](./general_setup13.png)

### Create LDAP Application & Provider

1. Create the LDAP Application under _Applications_ -> _Applications_ -> _Create With Wizard_ and name it `LDAP`.
   ![](./general_setup14.png)
   ![](./general_setup15.png)

### Assign LDAP permissions

1. Navigate to the LDAP Provider under _Applications_ -> _Providers_ -> `Provider for LDAP`.
2. Switch to the _Permissions_ tab.
3. Click the _Assign to new user_ button to select a user to assign the full directory search permission to.
4. Select the `ldapservice` user in the modal by typing in its username. Select the _Search full LDAP directory_ permission and click _Assign_

### Create LDAP Outpost

1. Create (or update) the LDAP Outpost under _Applications_ -> _Outposts_ -> _Create_. Set the Type to `LDAP` and choose the `LDAP` application created in the previous step.

:::info
The LDAP Outpost selects different providers based on their Base DN. Adding multiple providers with the same Base DN will result in inconsistent access
:::

### ldapsearch Test

Test connectivity by using ldapsearch.

:::info
ldapsearch can be installed on Linux system with these commands

```shell
sudo apt-get install ldap-utils -y # Debian-based systems
sudo yum install openldap-clients -y # CentOS-based systems
```

:::

```shell
ldapsearch \
  -x \
  -H ldap://<LDAP Outpost IP address>:<Port number 389> \ # In production it is recommended to use SSL, which also requires `ldaps://` as the protocol and the SSL port
  -D 'cn=ldapservice,ou=users,DC=ldap,DC=goauthentik,DC=io' \
  -w '<ldapuserpassword>' \
  -b 'DC=ldap,DC=goauthentik,DC=io' \
  '(objectClass=user)'
```

:::info
This query will log the first successful attempt in an event in the _Events_ -> _Logs_ area, further successful logins from the same user are not logged as they are cached in the outpost.
