SAML Chrome Panel:

Extends the (Chrome) Developer Tools, adding support for SAML Requests and Responses to be displayed in the Developer Tools window

This is an Open Source SAML debugger for Chrome. It operates as another panel in the Chrome Developer Tools section, which monitors the traffic in the current active tab. This panel is trying to replicate what the Firefox version of SAML Tracer does as there wasn’t a good enough one (or any) for Chrome at the time of writing this.

It is designed to display all network traffic, along with the request and response data. If there is a SAML request or response, then it will grab the message, format it nicely and show it to you in another tab.

This Chrome extension has proven useful to me at least twice.

Recently I was integrating ArgoCD and MongoDB Atlas with Okta. You can do it via SAML or via OIDC.

There’s always a chance of having one tiny configuration mistake, perhaps a typo or a missing field. I found:

• ArgoCD: a typo in the callback URL (foo-foo instead of foo)
• MongoDB Atlas: an acsError in the response (example, example): https://cloud.mongodb.com/okta/hooks/acsError: it was a certificate error. Instead of copying and pasting the certificate content (------ BEGIN CERTIFICATE ------), upload the file directly. The documentation (item 1.h.) notes so. Convert it to .pem prior to uploading it.
