Description

When logging into Artifactory using SAML (e.g. Okta), you may run into the below error in the browser.

{"errors":[{"status":400,"message":"{\"error\":\"Error occurred while trying to login using SAML. Check your Artifactory logs for more details.\"}"}]}

In Artifactory logs, you may see the below error message.

Signature verification failed.
Failed to verify response signature
org.opensaml.xmlsec.signature.support.SignatureException: Signature cryptographic validation not successful

When this error message appears, it suggests that the SAML response signature could not be verified during the login process. This issue commonly occurs when the certificate used to sign the SAML response is either invalid or has expired.
