In SAML, the binding allows signatures to appear in a number of different places. XML Signatures can't assume anything about the document structure for the standard it is used with, so instead it uses references to specify which part of the document the signature applies to. A given directory may be consistent about which node it signs, and the previous implementation was coded to assume the signature appears on the root element. However, with Azure the "Assertion" block is the signed part.

URL-encoded messages MAY be signed to provide origin authentication and integrity if the encoding method specifies a means for signing. If the message is signed, the Destination XML attribute in the root SAML element of the protocol message MUST contain the URL to which the sender has instructed the user agent to deliver the message. The recipient MUST then verify that the value matches the location at which the message has been received. ie, this URL is here to prevent someone from taking a login request for one IdP and using it for a different IdP. --- authnrequest.go | 1 + types.go | 1 + 2 files changed, 2 insertions(+) diff --git a/authnrequest.go b/authnrequest.go index 1bb1371..419c163 100644 --- a/authnrequest.go +++ b/authnrequest.go @@ -87,6 +87,7 @@ func (s *ServiceProviderSettings) GetAuthnRequest() *AuthnRequest { r.Issuer.Url = s.IDPSSODescriptorURL if s.SPSignRequest { r.Signature[0].KeyInfo.X509Data.X509Certificate.Cert = s.PublicCert() + r.Destination = s.IDPSSOURL } return r diff --git a/types.go b/types.go index a932584..f572d50 100644 --- a/types.go +++ b/types.go @@ -12,6 +12,7 @@ type AuthnRequest struct { ProtocolBinding string `xml:"ProtocolBinding,attr,omitempty"` AssertionConsumerServiceURL string `xml:"AssertionConsumerServiceURL,attr"` IssueInstant string `xml:"IssueInstant,attr"` + Destination string `xml:"Destination,attr,omitempty"` AssertionConsumerServiceIndex int `xml:"AssertionConsumerServiceIndex,attr,omitempty"` AttributeConsumingServiceIndex int `xml:"AttributeConsumingServiceIndex,attr,omitempty"` ForceAuthn string `xml:"ForceAuthn,attr,omitempty"` From 8ab58f4b5edf6a27153b4f8d538b1630b661d417 Mon Sep 17 00:00:00 2001 From: Sam Vilain Date: Thu, 10 Dec 2015 15:11:34 -0800 Subject: [PATCH 17/32] Allow AuthnRequests without name ID policy, auth context These elements are not required by the standard, and some directory servers will refuse requests with them set.

Being an OASIS standard, there are of course several ways this can be arranged with relation to signatures: the assertions can be signed and then encrypted, or the assertions can be encrypted and the whole message signed. This implementation allows for Assertion nodes to appear under EncryptedAssertion, which is the form that 'xmlsec1' expects and returns the plaintext versions, even though it doesn't conform to the XML schema.
