Source Repository : (https://github.com/phpList/phplist-plugin-simplesaml)

The easiest way to setup this plugin is through the plugins page (menu Config > Manage plugins) using the package URL https://github.com/phpList/phplist-plugin-simplesaml/archive/refs/heads/main.zip

The plugin may be enabled at this point or after the `SimpleSAMLPHP` config described below.

Plugin comes with a ready to use build of [`SIMPLESAMLPHP`](https://simplesamlphp.org/) (source code is slightly updated to work with phplist session logic). However, it is required that the server on which the `phpList` instance is running is configured to point to the `simplesamlphp` folder that comes in the plugin.

Essentially, `your-phplist-domain.ext/simplesamlphp` should point to the folder in `main/simplesaml/simplesamlphp` of the extension or a copy of it on your server.

By default, this plugin is configured to work with the `phpList`'s `Keyclaok` server. If you wish to change the identity provider, more configuration would be required. As described below.

In `main/simplesaml/simplesamlphp/config/authsources.php` the following parameters have to be set:

* entityID: The entityID is essentially the client ID which is specified in Keycloak or IDP
* idp: The IDP is the identifier for the IdP (Keycloak) which simplesaml would connect to.
* RelayState: The RelayState specifies where simplesamlphp should redirect to after a successful authentication. Basically it's like a callback url. This should simply be the URL from which the authentication started. Hence, a 'redirect back'.
* NameIDPolicy: The IdP is expected to return a NameID every successful auth session, this name ID is what identifies the user. Depending on the IdP this NameID might change every session. That makes it impossible to tract the user across session. So we have to said the NameIDPolicy to persistent essentially telling the IdP to send the same NameID all the time for the same user.

- In `main/simplesaml/simplesamlphp/config/config.php` the following parameters have to be set:

* `baseurlpath`: The `baseurlpath` refers to the base url the running `SimpleSAML` configuration. Depending on where simplesaml was installed, it could be a separate domain such as `phplist.com/simplesamlphp/www` or a path like `phplist.com/admin/simplesamlphp/www`.

_NB: The baseurlpath (which is essentially the simplesamlphp installation URI) is where the IdP returns the SAML response after a successful login. The SAML request would then be parsed and simplesamlphp would redirect back to the phplist URL that sent the request or the one set via the `RelayState` property in the config array of `authsources.php`_ within the config dir.

For more information about the custom configuration see [Readme config section](https://github.com/phpList/phplist-plugin-simplesaml#configuration))

See the README file on the GitHub page [https://github.com/phpList/phplist-plugin-simplesaml](https://github.com/phpList/phplist-plugin-simplesaml)

It is recommended to only enable the plugin only after the `SIMPLESAMLPHP` configs are set in the various configuration files described above and or in the [README](https://github.com/phpList/phplist-plugin-simplesaml#readme).

Configure Keycloak using this guide: https://resources.phplist.com/system/keycloak
Documentation: https://www.keycloak.org/documentation

You should verify that `yourdomain.com/simplesamlphp` for example `phplist.com/simplesamlphp` loads the `simplesamlphp` files correctly and that `phplist.com/simplesamlphp/www` loads the `simplesamlphp` UI like the one shown below.


You should have saml-certificate.pem and saml-private-key.pem files (certificate keys of keycloak client) in main/simplesaml/simplesamlphp/cert directory and certificate as string in main/simplesaml/simplesamlphp/metadata/saml20-idp-rempte.php certData value

After cloning the plugin in your plugin directory, you should login normally using your admin credentials and activate the plugin from the plugin management tab.
