Understanding SAML errors

Single Sign-On (SSO) using SAML can streamline user authentication, but sometimes errors pop up. These errors usually occur when there's a mismatch between your service provider and identity provider configurations. Let's break down common issues, error codes, and how you can troubleshoot them.

Common issues during SSO SAML authentication

Authentication errors often arise from configuration mismatches. Here are some common culprits:

• Incorrect x.509 certificates.

• Improper SAML response signatures.

• Typos or copy-paste mistakes in URLs.

• Missing or invalid parameters in your SAML assertions.

Examples of SAML error codes

What does a 401 error indicate?

A 401 error means there's an issue with your x.509 certificate. It could be incorrect or improperly configured. Another reason might be an improperly signed SAML response.

Additionally, understanding how server SDKs handle failures might provide insights into resolving these issues.

How to resolve a 924 error

A 924 error occurs when the account ID is missing in the assertion URL. This often results from typos or copy/paste mistakes. Double-check the assertion URL for accuracy and completeness.
