An available infrastructure for testing authentication and authorizationflows is often necessary in the Identity Management (IdM) field.Creating virtual environments for this purpose can result in highcosts in terms of time, effort, and resources required for buildingand maintaining these setups. Thus, GIdLab emerges as a laboratorydedicated to experimentation, provided by the Brazilian NationalEducation and Research Network (RNP). GIdLab offers specializedconsultancy in IdM with a tailor-made experimentation lab thatprovides a set of authorization and authentication infrastructuresand an eduroam environment ready to be used by researchers andsoftware developers. This article aims to describe GIdLab service,its infrastructure, the associated federations, the use of proxies, relatedprojects, identity decentralized testbed, and, finally, the resultsobtained over ten years of supporting experimentation.
