I have a Drupal site I am standing up for a client. I ve been asked to use Single Sign on using SAML2 (where I would be the service provider and my client would be the identity provider).
The best thing I have found so far has been either
SimpleSAMLPHP https://ow.feide.no/simplesamlphp:drupal
or
Shibboleth -- http://drupal.org/project/shib_auth
From looking at the documentation from these it looks like the Shibboleth module might be further ahead, but I m not sure that you can connect Shibboleth to SAML. Can you? Or do you need to connect to a Shibboleth identity provider?
The SimpleSAML module looks good, except it seems to require memcache which I would prefer to not use.
Thanks!
