CB Defense: HTTP 400 Error When Configuring SAML

Products

• Carbon Black Cloud Endpoint Standard (formerly Cb Defense)

Issue/Introduction

When attempting to configure SAML SSO in the web console, the configuration fails with the error "Request failed with status code 400" error message:

Request failed with status code 400

Environment

• CB Defense Web Console: All Versions
• SAML SSO

Cause

The X509 Certificate may not have been inserted correctly into the text field

Resolution

• When copying the text from the X509 certificate into the input field, sometimes white space or a carriage return is being copied over. Try copying the cert information over individually line by line into the console.
• Do not include the ---BEGIN CERTIFICATE--- and ---END CERTIFICATE---

Additional Information

• Pasting the X509 Cert into a text editor prior to the console can help ensure the entire cert is displayed as one line, as well as to remove carriage returns and spaces.
