SimpleSAMLphp-casserver is a CAS 1.0 and 2.0 compliant CAS server in the form of a SimpleSAMLphp module.


Install with composer

composer require simplesamlphp/simplesamlphp-module-casserver


Next thing you need to do is to enable the module: in config.php, search for the module.enable key and set casserver to true:

'module.enable' => [
    'casserver' => true,

See the config-templates folder for examples of configuring this module


To aid in debugging you can print out the CAS ticket xml rather then returning a ticket id. Enable debugMode in module_casserver.php and then add a query parameter debugMode=true to the CAS login url.

Logging in to would now print the xml for that service.

<?xml version="1.0">
<cas:serviceResponse xmlns:cas="">


Run phpcs to check code style

phpcs --standard=PSR12 lib/ tests/ www/ templates/

Run phpunit to test


Use docker php image to easily test between versions

docker run -ti --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp php:7.1-cli ./vendor/bin/phpunit

You can auto correct some findings from phpcs. It is recommended you do this after stage your changes (or maybe even commit) since there is a non-trivial chance it will just mess up your code.
