Jan 2015 - Oct 2016
SimpleSAMLphp is an application written in native PHP that deals with authentication.
Role in this project:Back-end Developer
Back-end DeveloperContributions:16 commits, 5 PRs, 9 comments in 1 year 9 months
Contributions summary:Jakob primarily focused on adding and synchronizing attribute mappings within the SimpleSAMLphp project. Their work involved modifying configuration files (`attributemap/*`) to include new attributes, particularly those related to the Swedish school federation (Skolfederation.se) and SIS (Swedish Standards Institute), TK 450 AG04. This involved adding new OIDs and attribute definitions across different mapping files. This activity directly enhances the project's compatibility with identity providers.
