Module does not have a Drupal 11 compatible version

This module depends on the Drupal Authentication SimpleSAMLphp module , which depends on SimpleSAMLphp which , at present , depends on Symfony 6.

SimpleSAMLphp will release a version compatible with the Symfony 7 only when Symfony 7 LTS will be release in November 2025.

For reference: https://symfony.com/releases/7.4

So this module is blocked and will not receive a Drupal 11compatible release until November this year.
