configuring saml-sample (SP) to work with SafeNet (IdP)

Hi,

I'm a bit new to SAML, so maybe there is something basic that I miss here.

I read the wiki page, and succeeded to operate the saml-example to work as SP in front of the SSOcircle (the IdP). Till here everything is fine.

However, I try now to make the saml-sample work in front of a "real world" IdP, such as SafeNet.
In the wiki, I saw how to configure the IdP metadata (3.2.2) - adding it in the XML. But how do I do so for SafeNet? how do I get their metadata XML file (if any)?
Do all IdP that support SAML provide somehow their metadata?
Maybe there is another way to configure the IdP?

Once I add the IdP metadata - I will have to upload my (the SP) metadata to SafeNet - this is something I've read about; but as I said, currently I am stuck in configuring the IdP metadata.

Hope someone can help me out here...

thanks!
