* postBindingLogout: Indicates if POST or redirect should be used for the logout requests.
This applies to both IdP-initiated logout, and Keycloak-initiated logout. If unset (for example when upgrading Keycloak), the setting is initially set to the same as postBindingResponse.
The flag is also set when importing IdP metadata.
* wantAssertionsSigned: This will toggle the flag in the SP Metadata Descriptor, and validate the signature if and only if "Validate signature" is selected.
* wantAssertionsEncrypted: This will simply require that the assertion is encrypted.
Default behavior is unchanged. The signature validation uses the original XML, and supports therefore an IdP that adds whitespace and line breaks between tags (for example OpenAM).
Active Directory Federation Services require that the subject name
matches KeyName element when present. While KeyName is beneficial for
Keycloak adapters, it breaks functionality for AD FS as the name
included there is a key ID, not certificate subject expected by AD FS.
This patch contains functionality that excludes KeyName from SAML
messages to identity providers. This behaviour should be made
configurable per client/identity provider and is prepared to do so,
however actual GUI changes are left for a separate patch.
A SAML brokered IdP can send unsolicited login response to the broker.
This commit adds a new GET/POST endpoint under [broker SAML
endpoint]/clients/{client_id}. Broken will respond to submission to
this new endpoint by looking up a SAML client with URL name equal to
client_id, and if found, it performs IdP-initiated SSO to that client.
Contrary to POST binding, signature of SAML protocol message sent using
REDIRECT binding is contained in query parameters and not in the
message. This renders <dsig:KeyName> key ID hint unusable. This commit
adds <Extensions> element in SAML protocol message containing key ID so
that key ID is present in the SAML protocol message.
Changes of SAML assertion creation/parsing that are required to allow
for validation of rotating realm key: signed SAML assertions and signed
SAML protocol message now contain signing key ID in XML <dsig:KeyName>
element.
