This repo is a modified fork of https://github.com/simplesamlphp/docker-simplesamlphp that sets up a test simplesamlphp-sp to connect to the Umich Identity Provider and provides nonprod example configuration.
To get started put the version of simplesamlphp you want to test in a folder named simplesamlphp per https://simplesamlphp.org/download. Then run docker-compose up -d. The ca folder should now contain a ca.pem file you can import in your browser for https access. Then point your browser at https://simplesamlphp.test.umich.localhost.
Note: SSO against the Umich Identity Provider will not work if the service has not been registered.
