What is SimpleSAMLphp?

SimpleSAMLphp is an award-winning application written in native PHP that deals with authentication. The project is led by UNINETT, 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:

  • SAML 2.0 as a Service Provider (SP)
  • SAML 2.0 as an Identity Provider (IdP)

However, it also supports some other identity protocols and frameworks, such as Shibboleth 1.3, 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 1.3, Shibboleth 2.2, PingID, Sun Federation Manager, Sun Federated Access Manager, Sun Access Manager, mod_mellon, CAS, etc.
