Roundcube OIDC

This plugin allows you to authenticate users to roundcube using an OpenID Connect 1.0 provider. There are three modes to run the plugin in:

1. Cleartext Password: The OIDC provider must supply the user's password in cleartext, which is then used to login to the IMAP server
2. Master Password: In this mode (also falls back to this), a master password is used to login to the IMAP server with the username obtained from OIDC
3. Master User: IMAP authentication is done using a master user (Dovecot) with a provided separator

Check the config.inc.php for more details on configuration.

SMTP

Note that unless cleartext passwords are provided, SMTP must necessarily be configured use no authentication or a master password

Installation

To install, get the plugin with composer in your roundcube directory

composer require radialapps/roundcube-oidc

Alternatively, some releases may be available as zipped packages here at GitHub. You need to unzip the package in your plugins directory and activate the plugin in the configuration.
