Splunk SOAR (f.k.a. Phantom)

Splunk Phantom SAML SAML2 authentication error Signature missing for response


We were configuring our phantom instance for saml sso login and we are encountering the following error.

SAML2 authentication error

Signature missing for response

We have already configured every field here.
Are we missing anything? Would we need to configure the idp chains or certficates.

Hi I am doing OKTA SAML integration with Phantom and getting the below error.

SAML2 Authentication Error'NoneType' object has no attribute 'require_signature

Can i know if any option to make the AuthnRequestsSigned="true to false? or any other suggestions.. I have tried disabling the signing on both okta and phantom

It sounds like your IdP is not signing the assertion.  You'll want to want to ensure that is occuring. You can install a browser plugin like SAML-TRACER  to view the assertions as they make their way to Phantom to ensure the signature is present. 

While it may not be your IDP - https://github.com/phantomcyber/phantom-community-projects/blob/master/Questions/SSO/SAML/PingFedera... has some details of setting up SSO with SAML (that doc is PingFederate specifically).
