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

14,317

If it might be helpful to someone in the future - I got it working now !!

I set all 3 URLs to the same one (as you suggested a week ago): https://srv101.watchdox.net:443/spring-security-saml2-sample/saml/SSO/alias/defaultAlias

so what is the difference, and why is it working now? because till now the URL I entered was http and not https (and without the 443): http://srv101.watchdox.net/spring-security-saml2-sample/saml/SSO/alias/defaultAlias

Okta is an IdP for SAML logins. I have a super-admin user of Okta.

I try to use Spring's saml-sample project as my SP (service-provider). When I configure it (spring-saml-sample) in the Okta system, I need to supply some data on my SP, such as "post back URL", "recipient" and "audience restriction".

After sniffing in Okta's docs, I found this:

Audience Restriction – This is the entity id of the Service Provider. It will be provided by the SP and must match exactly. Consult the SP documentation to get this information.

Recipient –Enter the service provider’s assertion consumer service URL . Consult the SP documentation to get this information. So I figured out that this URL should be: http://srv101.watchdox.net/spring-security-saml2-sample/saml/SSO/alias/defaultAlias

Post Back URL – This is the SAML SP endpoint (i.e. where your users will log in)

Destination for the SAML response – This is the intended destination of the saml assertion. Unless specified by the SP, this will typically be identical to the post back URL. Consult the SP documentation to get this information.

The Problem:

My app (spring-saml-sample) has a "welcome" page, where the user chooses the IdP he wants to login with. So I choose "Okta" IdP, and then i am redirected to the Okta to log-in (perfect till here), but after login, instead of redirecting me back to my app (to the protected resource), I stay in the Okta system and see their framework. I do see my app there. When I click on it, I get to my first page, to choose the IdP.

I believe the problem is with my URLs, or with the SAML response... Anyonw has an idea?

Pasted here the Request and response, if might be helpfull.

I pasted here the SAML requests and responses, in case it might be helpfull. Note that the Status Code in the response is "Success"!

What can be wrong? what am I missing?
