title: NextCloud

## What is NextCloud
|
|
|
|
From https://en.wikipedia.org/wiki/Nextcloud
|
|
|
|
:::note
|
|
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.
|
|
:::
|
|
|
|
:::warning
|
|
This setup only works, when NextCloud is running with HTTPS enabled.
|
|
:::
|
|
|
|
:::warning
|
|
In case something goes wrong with the configuration, you can use the URL `http://nextcloud.company/login?direct=1` to log in using the built-in authentication.
|
|
:::
|
|
|
|
## Preparation
|
|
|
|
The following placeholders will be used:
|
|
|
|
- `nextcloud.company` is the FQDN of the NextCloud install.
|
|
- `authentik.company` is the FQDN of the authentik install.
|
|
|
|
Create an application in authentik and note the slug, as this will be used later. Create a SAML provider with the following parameters:
|
|
|
|
- ACS URL: `https://nextcloud.company/apps/user_saml/saml/acs`
|
|
- Issuer: `https://authentik.company`
|
|
- Service Provider Binding: `Post`
|
|
- Audience: `https://nextcloud.company/apps/user_saml/saml/metadata`
|
|
- Signing Keypair: Select any certificate you have.
|
|
- Property mappings: Select all Autogenerated mappings.
|
|
|
|
You can of course use a custom signing certificate, and adjust durations.
|
|
|
|
## NextCloud
|
|
|
|
In NextCloud, navigate to `Settings`, then `SSO & SAML Authentication`.
|
|
|
|
Set the following values:
|
|
|
|
- Attribute to map the UID to.: `http://schemas.goauthentik.io/2021/02/saml/username`
|
|
- Optional display name of the identity provider (default: "SSO & SAML log in"): `authentik`
|
|
- Identifier of the IdP entity (must be a URI): `https://authentik.company`
|
|
- URL Target of the IdP where the SP will send the Authentication Request Message: `https://authentik.company/application/saml/<application-slug>/sso/binding/redirect/`
|
|
- Public X.509 certificate of the IdP: Copy the PEM of the Selected Signing Certificate
|
|
|
|
Under Attribute mapping, set these values:
|
|
|
|
- Attribute to map the displayname to.: `http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name`
|
|
- Attribute to map the email address to.: `http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress`
|
|
- Attribute to map the users groups to.: `http://schemas.xmlsoap.org/claims/Group`
|
|
|
|
## Group Quotas
|
|
|
|
Create a group for each different level of quota you want users to have. Set a custom attribute, for example called `nextcloud_quota`, to the quota you want, for example `15 GB`.
|
|
|
|
Afterwards, create a custom SAML Property Mapping with the name `SAML NextCloud Quota`.
|
|
Set the *SAML Name* to `nextcloud_quota`.
|
|
Set the *Expression* to `return user.group_attributes.get("nextcloud_quota", "1 GB")`, where `1 GB` is the default value for users that don't belong to another group (or have another value set).
|
|
|
|
## Admin Group
|
|
|
|
To give authentik users admin access to your NextCloud instance, you need to create a custom Property Mapping that maps an authentik group to "admin". It has to be mapped to "admin" as this is static in NextCloud and cannot be changed.
|
|
|
|
Create a SAML Property mapping with the SAML Name "http://schemas.xmlsoap.org/claims/Group" and this expression:
|
|
|
|
```python
|
|
for group in user.ak_groups.all():
|
|
yield group.name
|
|
if ak_is_group_member(request.user, name="<authentik nextcloud admin group's name>"):
|
|
yield "admin"
|
|
```
|
|
|
|
Then, edit the NextCloud SAML Provider, and replace the default Groups mapping with the one you've created above.
