We had previously defined all environments to use a wildcard domain like .example.org for all SimpleSAMLPHP cookies. This caused all the environments under the same domain to have overlapping SSO logins, which often broke the login altogether for users using the test environments.

We wanted to log SimpleSAMLPHP stuff to Filebeat in Amazee Lagoon environment. This could've worked with using the stderr logging method, but for some reason it didn't seem to consistently work and we wanted to divide the logs to fields to make them more usable.
