  Problem 1
    - simplesamlphp/simplesamlphp[v1.19.0, ..., v1.19.1] require php >=7.1 <8.0 -> your php version (8.1.18) does not satisfy that requirement.
    - simplesamlphp/simplesamlphp[v1.19.2, ..., 1.19.9] require symfony/console ^4.4 || ^5.0 -> found symfony/console[v4.4.0, ..., v4.4.49, v5.0.0, ..., v5.4.36] but these were not loaded, likely because it conflicts with another require.
    - simplesamlphp/simplesamlphp v1.19.6 requires gettext/gettext v4.x-dev#3e7460f8d9c90174824e3f39240bd578bb3d376a -> found gettext/gettext[4.x-dev] but it does not match your minimum-stability.
    - simplesamlphp/simplesamlphp[2.1.0, ..., v2.1.5] require twig/twig ^3.5 -> found twig/twig[v3.5.0, ..., v3.8.0] but these were not loaded, likely because it conflicts with another require.
    - simplesamlphp/simplesamlphp v2.2.0 requires symfony/console ^6.4 -> found symfony/console[v6.4.0, ..., v6.4.4] but these were not loaded, likely because it conflicts with another require.
    - drupal/simplesamlphp_auth 4.0.0 requires simplesamlphp/simplesamlphp ^1.19 || ^2.1 || dev-simplesamlphp-2.1 -> satisfiable by simplesamlphp/simplesamlphp[v1.19.0, ..., 1.19.9, 2.1.0, ..., v2.2.0].
    - Root composer.json requires drupal/simplesamlphp_auth ^4.0 -> satisfiable by drupal/simplesamlphp_auth[4.0.0].

Proposed resolution

Need to add supported simplesamlphp/simplesamlphp dependency simplesamlphp/simplesamlphp:2.0.0-beta99
