What is the SAML Assertion Consumer URL for an AD FS 2.0 Service Provider

Question

I am configuring a service provider to use SSO authentication. I will be using AD FS 2.0 for this.

What is the URL for the SAML Assertion Consumer that I need to give to the IdP?

I think it may be something like one of these:

• https://abc.com/adfs/ls/
• https://abc.com/_trust/

but I'm not sure. Any ideas?

Solution

When ADFS 2.0 is used as a service provider (i.e. RP STS) it consumes assertions at URLs like https://sts.contoso.com/adfs/ls/ .

The assertion consumer service URL is specific to the service provider. If ADFS is the service provider then the metadata URLs publish the assertion consumer URLs as follows.

<AssertionConsumerService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Location="https://sts.contoso.com/adfs/ls/" index="0" isDefault="true" /> 
  <AssertionConsumerService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Artifact" Location="https://sts.contoso.com/adfs/ls/" index="1" /> 
  <AssertionConsumerService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect" Location="https://sts.contoso.com/adfs/ls/" index="2" /> 

And here is some sample assertion consumer service URLs from another test site for comparison. http://www.testshib.org/metadata/testshib-two-metadata.xml

<AssertionConsumerService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Location="https://sp.testshib.org/Shibboleth.sso/SAML2/POST" index="1" isDefault="true" xmlns="urn:oasis:names:tc:SAML:2.0:metadata" />

<AssertionConsumerService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST-SimpleSign" Location="https://sp.testshib.org/Shibboleth.sso/SAML2/POST-SimpleSign" index="2" xmlns="urn:oasis:names:tc:SAML:2.0:metadata" />
<AssertionConsumerService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Artifact" Location="https://sp.testshib.org/Shibboleth.sso/SAML2/Artifact" index="3" xmlns="urn:oasis:names:tc:SAML:2.0:metadata" />
<AssertionConsumerService Binding="urn:oasis:names:tc:SAML:1.0:profiles:browser-post" Location="https://sp.testshib.org/Shibboleth.sso/SAML/POST" index="4" xmlns="urn:oasis:names:tc:SAML:2.0:metadata" />

<AssertionConsumerService Binding="http://schemas.xmlsoap.org/ws/2003/07/secext" Location="https://sp.testshib.org/Shibboleth.sso/ADFS" index="6" xmlns="urn:oasis:names:tc:SAML:2.0:metadata" />
