This repository contains the simplified code of It is focused on what NRENs need, so now it is easy to host a SAML Identity Provider as a Service for the institutes of your NREN.

Using this service is free, but donations are welcome and will go towards further development of this project. Use the wallet addresses below to donate.

Thank you for your support and generosity!


  • VM with docker hosting environment
  • relational database service
  • logging service
  • smtp service
  • some persistent storage
  • a dedicated domain for your service
  • a wildcard certificate for your choosen domain ($SAMLIDP_HOSTNAME) for this service (the main domain will host your service, the third level domains will host the IdPs)
  • open 80/443 ports for incoming traffic and open for outgoing traffic on your firewall


  1. Clone this repository
  2. Grab your wildcard certificate from your CA, use wildcard_certificate.key/wildcard_certificate.crt names for them.
  3. Encrypt the key: openssl aes256 -md sha256 -a -salt -k $VAULT_PASS -in wildcard_certificate.key -out wildcard_certificate.key.enc then put the certificate and the encrypted key into conf/credentials folder. You will need this $VAULT_PASS for starting the app, so save it. Depending your CA but you may have to merge the certificatechain into wildcard_certificate.crt.
  4. Configure storage service in app/app/config/config.yml and logging service in app/app/config/config_prod.yml. There are lots of Monolog handlers you can use directly.
  5. Generate a self-signed certificate for the attribute release checking service, which will be deployed to attributes.$SAMLIDP_HOSTNAME. cd conf/credentials && openssl req -new -newkey rsa:2048 -x509 -days 3652 -nodes -out attributes.$SAMLIDP_HOSTNAME.crt -keyout attributes.$SAMLIDP_HOSTNAME.key. Important: value of CN must be $SAMLIDP_HOSTNAME. In case the attribute release checking service page fails to open and you get an error Unable to load private key from file "/app/vendor/simplesamlphp/simplesamlphp/cert/attributes.$SAMLIDP_HOSTNAME make sure the key file has appropriate read permissions and build the image again.
  6. Build the image: docker build -t samli/nren .
  7. Edit docker-compose.yml, fill the values environment variables. (See details below)
  8. Start the service: docker-compose up
  9. Connect to your samlidp service on your choosen domain via your browser
  10. Register an admin user, then run in the container: app/bin/console fos:user:promote admin ROLE_SUPER_ADMIN. After logout and login this user can be able to edit all the registered IdPs and users.
  11. Test the app, register an IdP, add users, test against an SP...etc


  1. You can find the templates at app/app/src/AppBundle/Resources/views/default, the used english texts at app/app/Resources/AppBundle/translations. You can make other translations easily without modifying original templates.
  2. Additionally you should customize text of mails (app/app/src/AppBundle/Resources/views/IdPUser/*.txt) and login theme of IdP (misc/themesamlidpio).
  3. While you are doing this customization, you should attach these folders as volumes to your container, so you can see the changes on-the-fly. If you are ready, rebuild then restart the image.
