Yes is does support SAML 2.0. I always use SAML Tracer a firefox plugin to test the SSO. And do make sure that the lognode is set to trace for the SAML module otherwise you will not get all the information about what might go wrong.

Hi Samarth,
Check out this posted workaround that may be related to your issue.

I think the newest version of the SAML module in the app store already has this fix applied, so you may just have to update the module.
Best,
Horace
