## What is Roundcube
|
|
|
|
> **Roundcube** is a browser-based multilingual IMAP client with an application-like user interface.
|
|
> It provides full functionality you expect from an email client, including MIME support, address book, folder manipulation, message searching and spell checking
|

|
|
|
|
This integration describes how to use Roundcube's oauth support with authentik to automatically sign into an email account.
|
|
The mail server must support XOAUTH2 for both SMTPD and IMAP/POP. Postfix SMTP server can also use Dovecot for authentication which provides Postfix with xoauth2 capability without configuring it separately.
|
|
|
|
## Preparation
|
|
|
|
The following placeholders will be used:
|
|
|
|
- `authentik.company` is the FQDN of the authentik install.
|
|
|
|
Create a new oauth2 Scope Mapping which does not return the 'group' values and associate this mapping
|
|
in the provider settings instead of the default oauth mapping.
|
|
|
|
Under _Customization_ -> _Property Mappings_, create a _Scope Mapping_. Give it a name like "oauth2-Scope-dovecot". Set the scope name to `dovecotprofile` and the expression to the following
|
|
|
|
```
|
|
return {
|
|
"name": request.user.name,
|
|
"given_name": request.user.name,
|
|
"family_name": "",
|
|
"preferred_username": request.user.username,
|
|
"nickname": request.user.username,
|
|
#DO NOT INCLUDE groups
|
|
}
|
|
```
|
|
|
|
Create an application in authentik. Create an _OAuth2/OpenID Provider_ with the following parameters:
|
|
|
|
- Client Type: `Confidential`
|
|
- Scopes: OpenID, Email, and the scope you created above
|
|
- Signing Key: Select any available key
|
|
|
|
## Roundcube Configuration
|
|
|
|
```
|
|
$config['oauth_provider'] = 'generic';
|
|
$config['oauth_provider_name'] = 'authentik';
|
|
$config['oauth_client_id'] = '<Client ID>';
|
|
$config['oauth_client_secret'] = '<Client Secret>';
|
|
$config['oauth_auth_uri'] = 'https://authentik.company/application/o/authorize/';
|
|
$config['oauth_token_uri'] = 'https://authentik.company/application/o/token/';
|
|
$config['oauth_identity_uri'] = 'https://authentik.company/application/o/userinfo/';
|
|
$config['oauth_scope'] = "email openid dovecotprofile";
|
|
$config['oauth_auth_parameters'] = [];
|
|
$config['oauth_identity_fields'] = ['email'];
|
|
```
|
|
|
|
## Dovecot Configuration
|
|
|
|
Add xoauth2 as an authentication mechanism and configure the following parameters in your Dovecot configuration.
|
|
|
|
```
|
|
tokeninfo_url = https://authentik.company/application/o/userinfo/?access_token=
|
|
introspection_url = https://<Client ID>:<Client Secret>@authentik.company/application/o/introspect/
|
|
introspection_mode = post
|
|
force_introspection = yes
|
|
active_attribute = active
|
|
active_value = true
|
|
username_attribute = email
|
|
tls_ca_cert_file = /etc/ssl/certs/ca-certificates.crt
|
|
```
|
|
|
|
:::note
|
|
With this setup Dovecot can also be used with other email clients that support XOAUTH2 authentication, however
|
|
most available software (including Fair Email for Android and Thunderbird) only come with support for Gmail,
|
|
Outlook etc with no way to configure custom email servers.
