[{title SAML development setup} {priority 920}] | index, follow |
Set up a development SAML idP
Note: This guide is targeted only at development with OpenProject. For the SAML configuration guide, please see this URL: https://www.openproject.org/docs/system-admin-guide/authentication/saml/
To test the SAML integration in your development setup, you can use the following repository: https://github.com/kristophjunge/docker-test-saml-idp
The following guide will provide insights how to set it up in your OpenProject development instance.
Prerequisites
- A working docker installation
- A development setup of OpenProject (or any other configurable installation)
Running the SAML idP
We need to run the SimpleSAMLphp idP contained in the docker container. We only extend it slightly by giving the user configuration file more attributes so that OpenProject can pick it up. The default users configuration is lacking some of the default attributes OpenProject expects.
Create a new folder saml-idp
and switch to it
mkdir saml-idp && cd saml-idp
Create a file users.php
with the following content
<?php
$config = array(
'admin' => array(
'core:AdminPassword',
),
'example-userpass' => array(
'exampleauth:UserPass',
'user1:user1pass' => array(
'uid' => 'user1',
'givenName' => 'foo',
'sn' => 'bar',
'eduPersonAffiliation' => array('group1'),
'email' => 'user1@example.com',
),
'user2:user2pass' => array(
'uid' => 'user2',
'givenName' => 'user',
'sn' => 'second',
'eduPersonAffiliation' => array('group2'),
'email' => 'user2@example.com',
),
),
);
You can now run the docker container and the updated configuration with this command.
docker run \
-p 8080:8080 \
-p 8443:8443 \
-e SIMPLESAMLPHP_SP_ENTITY_ID=http://localhost:3000 \
-e SIMPLESAMLPHP_SP_ASSERTION_CONSUMER_SERVICE=http://localhost:3000/auth/saml/callback \
-e SIMPLESAMLPHP_SP_SINGLE_LOGOUT_SERVICE=http://localhost:3000/auth/saml/slo \
-v $(pwd)/users.php:/var/www/simplesamlphp/config/authsources.php \
--network host \
kristophjunge/test-saml-idp
If you're not using a development installation of OpenProject, you'll need to change the ENV variables slightly:
docker run \
-p 8080:8080 \
-p 8443:8443 \
-e SIMPLESAMLPHP_SP_ENTITY_ID=http://<YOUR OPENPROJECT HOSTNAME> \
-e SIMPLESAMLPHP_SP_ASSERTION_CONSUMER_SERVICE=http://<YOUR OPENPROJECT HOSTNAME>/auth/saml/callback \
-e SIMPLESAMLPHP_SP_SINGLE_LOGOUT_SERVICE=http://<YOUR OPENPROJECT HOSTNAME>/auth/saml/slo \
-v $(pwd)/users.php:/var/www/simplesamlphp/config/authsources.php \
--network host \
kristophjunge/test-saml-idp
Configure OpenProject for SAML
On the OpenProject side, you'll have to configure SAML to connect to the just started idP service:
Here's a minimal configuration that you can put into config/configuration.yml
default:
saml:
name: "saml"
display_name: "simplesaml-docker"
# Use the default SAML icon
icon: "auth_provider-saml.png"
# omniauth-saml config
assertion_consumer_service_url: "http://localhost:3000/auth/saml/callback"
issuer: "http://localhost:3000"
idp_cert_fingerprint: "119b9e027959cdb7c662cfd075d9e2ef384e445f"
idp_sso_target_url: "http://localhost:8080/simplesaml/saml2/idp/SSOService.php"
idp_slo_target_url: "http://localhost:8080/simplesaml/saml2/idp/SingleLogoutService.php"
attribute_statements:
email: ['email']
login: ['uid']
first_name: ['givenName']
last_name: ['sn']
Here, again you will have to change the hostname localhost:3000
with the hostname of your OpenProject installation, and the iDP host name if you're not running both locally. I'd recommed to run both locally though for simplicity.
Restart OpenProject and you'll see a login button "simplesaml-docker". You will redirected to the simplesaml-php docker container and can login with either:
- login: user1, password: user1pass
- login: user2, password: user2pass
