Nextcloud Integration with AuthPoint

Deployment Overview

This document describes how to set up multi-factor authentication (MFA) for Nextcloud with AuthPoint as an identity provider. Nextcloud must already be configured and deployed before you set up MFA with AuthPoint.

Nextcloud Authentication Data Flow with AuthPoint

AuthPoint communicates with various cloud-based services and service providers with the SAML protocol. This diagram shows the data flow of an MFA transaction for Nextcloud.

Before You Begin

Before you begin these procedures, make sure that:

Configure Nextcloud

To start, you must download the metadata file from the Certificate Management page in the AuthPoint management UI. After you have that, you can configure Nextcloud.

  1. Log in to WatchGuard Cloud.
  2. From the navigation menu, select Configure > AuthPoint. If you have a Service Provider account, you must select an account from Account Manager.
  3. Select Resources.
  4. Click Certificate.

  1. Next to AuthPoint certificate you will associate with your resource, click and select Download metadata. We recommend that you choose the certificate with the latest expiration date.

    The AuthPoint metadata provides your resource, in this case Nextcloud, with information necessary to identify AuthPoint as a trusted identity provider.

  1. Log in to Nextcloud with an administrative account.
  2. From the navigation menu, select SSO & SAML authentication.
  3. Click Use built-in SAML authentication.

  1. In the General section, in the Attribute to map the UID to text box, type username.
  2. In the next text box, type a display name. In our example, we type AuthPoint.
  3. In the Identity Provider Data section, click Show optional Identity Provider settings.
  4. Open the AuthPoint metadata file you downloaded and find these values:
    • entityID
    • SingleSignOnService Location
    • SingleLogoutService Location
    • X509Certificate
  5. In Nextcloud, in the Identifier of the IdP entity text box, paste the entityID value from the AuthPoint metadata file.
  6. In the URL Target of the IdP where the SP will send the Authentication Request Message text box, paste the SingleSignOnService Location value from the AuthPoint metadata file.
  7. In the URL Location of the IdP where the SP will send the SLO Request text box, paste the SingleLogoutService Location value from the AuthPoint metadata file.
  8. In the Public X.509 certificate of the IdP text box, paste the X509Certificate value from the AuthPoint metadata file.
  9. Click Download metadata XML.

Configure AuthPoint

Before AuthPoint can receive authentication requests from Nextcloud, you must add a SAML resource in AuthPoint. You must also create an authentication policy for the Nextcloud resource to determine which users can authenticate and log in to Nextcloud and which authentication methods they can use (Push, QR code, and OTP).

Add a SAML Resource in AuthPoint

From the AuthPoint management UI:

  1. From the navigation menu, select Resources.
  2. From the Choose a Resource Type drop-down list, select SAML. Click Add Resource.

  1. On the SAML page, in the Name text box, type a name for this resource. In our example
  2. From the Application Type drop-down list, select Nextcloud.
  3. In the Service Provider Entity ID text box, type or paste the entityid value from the Nextcloud metadata file .
  4. In the Assertion Consumer Service text box, type or paste the AssertionConsumerService URL from the Nextcloud metadata file.
  5. From the AuthPoint Certificate drop-down list, select the certificate to associate with your resource. This must be the same certificate that you downloaded the metadata for in the previous section.
  6. Click Save.

Add a Group in AuthPoint

You must have at least one user group in AuthPoint to configure MFA. If you already have a group, you do not have to add another group.

To add a group to AuthPoint:

  1. From the navigation menu, select Groups.
  2. Click Add Group.
    The New Group page appears.

  1. In the Name text box, type a descriptive name for the group.
  2. (Optional) In the Description text box, type a description of the group.

  1. Click Save.
    Your group is listed on the Groups page.

Add an Authentication Policy to AuthPoint

Authentication policies specify which resources users can authenticate to and which authentication methods they can use (Push, QR code, and OTP).

You must have at least one authentication policy in AuthPoint that includes the Nextcloud resource. If you already have authentication policies, you do not have to create a new authentication policy. You can add this resource to your existing authentication policies.

Users that do not have an authentication policy for a specific resource cannot authenticate to log in to that resource.

To configure an authentication policy:

  1. From the navigation menu, select Authentication Policies.
  2. Click Add Policy.

Screenshot of the Add Policy button on the Authentication Policies page.

  1. Type a name for this policy.
  2. From the Select the authentication options drop-down list, select Authentication options and select which authentication options users can choose from when they authenticate.

    For SAML resources, if you select more than one authentication option, users must select one of the available options when they authenticate. For example, if you select OTP and Push, users can choose to type their OTP or approve a push to authenticate. You cannot require that they do both.

  1. Select which groups this policy applies to. You can select more than one group. To configure this policy to apply to all groups, select All Groups.
  2. Select the resource that you created in the previous section. If you want this policy to apply to additional resources, select each resource this policy applies to. To configure this policy to apply to all resources, select All Resources.

Screenshot of the Add Policy page with the groups and resources selected

  1. (Optional) If you have configured policy objects such as a Network Location, select which policy objects apply to this policy. When you add a policy object to a policy, the policy only applies to user authentications that match the conditions of the policy objects. For example, if you add a Network Location to a policy, the policy only applies to user authentications that come from that Network Location. Users who only have a policy that includes a Network Location do not get access to the resource when they authenticate outside of that Network Location (because they do not have a policy that applies, not because authentication is denied).

    If you configure policy objects, we recommend that you create a second policy for the same groups and resources without the policy objects. The policy with the policy objects should have a higher priority.

Screenshot of the Policy Objects drop-down list.

  1. Click Save.
    Your policy is created and added to the end of the policy list.

    When you create a new policy, we recommend that you review the order of your policies. AuthPoint always adds new policies to the end of the policy list.

Screenshot of the Save button on the Add Policy page.

Add Users to AuthPoint

Before you assign users to a group, you must add the users to AuthPoint. There are two ways to add AuthPoint user accounts:

  • Sync users from an external user database
  • Add local AuthPoint users

Each user must be a member of a group. You must add at least one group before you can add users to AuthPoint.

Test the Integration

To test AuthPoint MFA with Nextcloud, you can authenticate with a mobile token on your mobile device. For SAML resources, you can choose any method (push, QR code, or one-time password).

In this example, we show the push authentication method (users receive a push notification in the mobile app that they must approve to authenticate).

  1. In a web browser, go to the Nextcloud URL.
  2. Type your email address or AuthPoint user name. Click Next.
  3. If required, in the Password text box, type your password.
  4. For the authentication method, select Push.
  5. Click Send.
  6. Approve the authentication request that is sent to your mobile device.
    You are logged in to Nextcloud.
