SimpleSAMLphp is an award-winning application written in native PHP that deals with authentication. The community-led project has a large user base, a helpful user community and a large set of external contributors. The main focus of SimpleSAMLphp is providing support for:
However, it also supports some other identity protocols and frameworks, such as A-Select, CAS, OpenID, WS-Federation or OAuth, and is easily extendable, so you can develop your own modules if you like.
With the memcache session handler, SimpleSAMLphp scales pretty well. A replication layer is built upon memcache, such that an unlimited number of SimpleSAMLphp web front-ends can work with a back-end matrix of memcache servers with both replication (fail-over) and load-balancing.
SimpleSAMLphp is tested with several other federation software implementations. Among others; Shibboleth:, PingID, Sun Federation Manager, Sun Federated Access Manager, Sun Access Manager, mod_mellon, CAS, etc. If someone discovers incompatibility issues, we try to sort them out as fast as possible if reported properly through the issue tracker.
