Integração do Nextcloud com Authentik LDAP

Em 09/04/2026
What is Nextcloud
Nextcloud is a suite of client-server software for creating and using file hosting services. Nextcloud is free and open-source, which means that anyone is allowed to install and operate it on their own private server devices.
-- https://nextcloud.com/
WARNING
If you require server side encryption, you must use LDAP. OpenID and SAML will cause irrevocable data loss. Nextcloud server side encryption requires access to the user's cleartext password, which Nextcloud has access to only when using LDAP because the user enters their password directly into Nextcloud.
CAUTION
This setup only works when Nextcloud is running with HTTPS enabled. See here on how to configure this.
INFO
If there’s an issue with the configuration, you can log in using the built-in authentication by visiting http://nextcloud.company/login?direct=1.
Configuration methods
It is possible to configure Nextcloud to use OIDC, SAML, or LDAP for authentication. Below are the steps to configure each method.
OIDC
SAML
LDAP

Preparation
The following placeholders are used in this guide:
nextcloud.company is the FQDN of the Nextcloud installation.
authentik.company is the FQDN of the authentik installation.
INFO
This documentation lists only the settings that you need to change from their default values. Be aware that any changes other than those explicitly mentioned in this guide could cause issues accessing your application.
Create an application and provider in authentik
Log in to authentik as an administrator and open the authentik Admin interface.
Navigate to Applications > Applications and click Create with Provider to create an application and provider pair. (Alternatively you can first create a provider separately, then create the application and connect it with the provider.)
Application: provide a descriptive name, an optional group for the type of application, the policy engine mode, and optional UI settings.
Choose a Provider type: select LDAP as the provider type.
Configure the Provider: provide a name (or accept the auto-provided name) and the bind flow to use for this provider
Configure Bindings (optional): you can create a binding (policy, group, or user) to manage the listing and access to applications on a user's My applications page.
Click Submit to save the new application and provider.
Create an LDAP outpost
Log in to authentik as an admin, and open the authentik Admin interface.
Navigate to Applications > Outposts and click Create.
Name: provide a suitable name for the outpost.
Type: 
LDAP
Under applications, add the newly created Nextcloud application to Selected Applications.
Click Create.
Nextcloud configuration
In Nextcloud, ensure that the LDAP user and group backend app is installed.
Log in to Nextcloud as an administrator.
Navigate to Settings > LDAP user and group backend and configure the following settings:
On the Server tab:
Click the + icon and enter the following settings:
Host: enter the hostname/IP address of the authentik LDAP outpost preceded by 
ldap:// or 
ldaps://. If using LDAPS you will also need to specify the certificate that is being used.
Port: 
389 or 
636 for secure LDAP.
Under Credentials, enter the Bind DN of the authentik LDAP provider and the associated user password.
Under Base DN, enter the Search base of the authentik LDAP provider.
On the Users tab:
Set Only these object classes to 
Users.
On the LDAP/AD integration tab:
Uncheck LDAP/AD Username.
Set Other Attributes to 
cn.
Click Expert in the top right corner and enter these settings:
Internal Username Attribute:

Click Advanced in the top right corner and enter these settings:
Under Connection Settings:

Under Directory Settings:
User Display Name Field:

Base User Tree: enter the Search base of the authentik LDAP provider.
Group Display Name Field:

Under Special Attributes:
Email Field:

On the Groups tab:

Select the authentik groups that require Nextcloud access.
INFO
If Nextcloud is behind a reverse proxy, force HTTPS by adding 
'overwriteprotocol' => 'https' to the Nextcloud 
config/config.php file. See the Nextcloud admin manual for more details.
Configuration verification
To confirm that authentik is properly configured with Nextcloud, log out and log back in using LDAP credentials. If successful you will then be redirected to the Nextcloud dashboard.
